configure.ac: also search libcrypt through pkg-config
libxcrypt provides a libcrypt.pc file so use it if available as this
will allow to retrieve the library path (e.g.
-L/home/buildroot/output/host//riscv64-buildroot-linux-musl/sysroot/usr/lib)
which is useful when cross-compiling and will avoid the following build
failure on buildroot:
/home/buildroot/autobuild/run/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/riscv64-buildroot-linux-musl/10.2.0/../../../../riscv64-buildroot-linux-musl/bin/ld: .libs/passverify.o: in function `.L30':
passverify.c:(.text+0x368): undefined reference to `crypt_checksalt'
Fixes:
