Commit d0c42dfa "pam: bind Linux-PAM locales from pam-specific folder
(upstream patch)" added autoreconfHook269 into one of the postPatch
phases.
This clobbered the change applied by `suid-wrapper-path.patch` as it was
patching Makefile.in.
As a result `nixosTests.sway` test started failing as:
check pass; user unknown
Running `swaylock` on real system exhibited the same result.
As `suid-wrapper-path.patch` is clobbered we were running non-suid
version of `unix_chkpwd`:
/nix/store/...-linux-pam-1.5.2/sbin/unix_chkpwd
instead of SUID-wrapped
/run/wrappers/bin/unix_chkpw
The fix is trivial: move the patch from auto-generated file to
`Makefile.am`.
