any fake value.

Remove MAINTAINER= lines from individual Makefiles in favor of the
MAINTAINER file (which already had entries for sendmail).

Prevent a 'make SHARED=symlinks install' followed by 'make install' from
failing by removing the symlink before trying to install the actual files.

Unbreak installworld. Revision 1.41 of src/usr.bin/xinstall/xinstall.c
made the usage here incorrect.

Note that the change to install may cause other things to break, such as
the advice in src/etc/defaults/make.conf:

# Compare before install
#INSTALL=install -C

If users actually use this, any ${INSTALL} -d invocations in an installworld
will also fail.
