Clayton Craft 179b7c2ab5 pam_systemd: acquire inhibit lock when inhibit= is specified
This adds a new function, acquire_inhibit_lock, that takes a logind
inhibitor lock for the duration of the PAM session. The lock fd is
stored in PAM data with pam_cleanup_close. In pam_sm_close_session, the
lock is released explicitly by passing NULL to pam_set_data, which
triggers the registered cleanup function immediately rather than waiting
for pam_end.

The inhibit type and reason string can also be configured via the
XDG_SESSION_INHIBIT and XDG_SESSION_INHIBIT_WHY environment variables,
which take precedence over the module arguments.

Fixes: #20654
