Revert "wpa: Import wpa_supplicant/hostapd commit 14ab4a816"

This reverts commit 266f97b5e9a7958e365e78288616a459b40d924a, reversing
changes made to a10253cffea84c0c980a36ba6776b00ed96c3e3b.

A mismerge of a merge to catch up to main resulted in files being
committed which should not have been.

contrib/wpa: Complete the revert of Import wpa.

Remove files added by b51f459a2098622c31ed54f5c1bf0e03efce403b.
The util/config.c conflicts with wpa_supplicant/config.c causing
the linker error.

The proper approach would have been to prepare the wpa build to
build the various subdirectories into .a libraries. SRCS makes no
distinction between files of the same name. The MFV accounted for this
but the revert failed to remove the additional files, including the
conflicting utils/config.c.

Revert wpa import.

b51f459a2098622c31ed54f5c1bf0e03efce403b resulted in a mismerge
due to having to do a remerge because my tree was over a week out of
date. Changes that were made to fix the build were lost in the remerge
resulting in build errors that were fixed a week ago.
