meson: Fix failure to detect bsd_auth.h presence

anarazel · anarazel · commit b64d83115cba · 2025-02-12T08:15:53.000-05:00
bsd_auth.h file needs to be included after 'sys/types.h', as documented in https://man.openbsd.org/authenticate.3 The reason a similar looking stanza works for autoconf is that autoconf automatically adds AC_INCLUDES_DEFAULT, which in turn includes sys/types.h. Backpatch to all versions with meson support.
