meson: fallback to libcrypt detection outside of pkg-config

Browse Source 
Much like PAM, not all implementations of libcrypt provide a pkg-config
file, and hence we can't find it using the old logic.

Let's fall back to the standard AC_SEARCH_LIBS-style check if the pkg-config-style
detection fails.

This fixes finding e.g. musl's libcrypt.
