meson: allow to fallback to use libxcrypt.pc or glibc's libcrypt

Some distributions still use glibc's libcrypt. In that case, libcrypt.pc
does not exist and dependency() will fail.
Also, even if libxcrypt is used, there may not be a symlink
from libcrypt.pc to libxcrypt.pc. So, let's add a secondary name.

Follow-up for d625f717db.

Fixes #28289.
