build-sys: only use AM_PATH_LIBGCRYPT macro if it exists
If gcrypt's m4 macro files aren't installed, with this change, gcrypt
will be disabled --- unless gcrypt support was explicitly requested by
passing --enable-gcrypt to configure, in which case it will fail.
Without this change, autoconf would fail either way with not being able
to resolve AM_PATH_LIBGCRYPT.
