ssh: move common Makefile boilerplate to a new ssh.mk

This moves SSHDIR and ssh_namespace.h handling to a common location,
and will simplify future work such as adding U2F support (D32509).

openssh: update to OpenSSH v8.7p1

Some notable changes, from upstream's release notes:

- sshd(8): Remove support for obsolete "host/port" syntax.
- ssh(1): When prompting whether to record a new host key, accept the key
fingerprint as a synonym for "yes".
- ssh-keygen(1): when acting as a CA and signing certificates with an RSA
key, default to using the rsa-sha2-512 signature algorithm.
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures.
- ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one).
- ssh(1): this release enables UpdateHostkeys by default subject to some
conservative preconditions.
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used.

Additional integration work is needed to support FIDO/U2F in the base
system.

Deprecation Notice
------------------

OpenSSH will disable the ssh-rsa signature scheme by default in the
next release.

Replace unneeded manual dependency on header by adding it to SRCS.

bsd.lib.mk and bsd.prog.mk already depend all objs on headers in SRCS if
there is not yet a depend file. The headers in SRCS are never built or
installed. After 'make depend' the header was already added as a proper
dependency on the objects where needed.

Update Makefiles for OpenSSH 3.7.1p2.

Explicitly add libz and libcrypto to LDADD for any ssh utilities missing

I have a more permanent solution to this problem in the works, but I

also makes the ssh build more along the lines of what the openssh-portable

Fix style and unbreal static build.

Now that cross-tools ld(1) has been fixed to look for dynamic
dependencies in the correct place, record the fact that -lssh

secure/ build fixes:

- SSHDIR (formerly SSHSRC) is now shared between all SSH modules.
New LIBSSH is introduced for libssh.a (an internal static lib).
Previously, build without prior `obj' was broken; SSH modules
always looked for libssh.a in ${.OBJDIR}. Also, the dependancies
