Subject: [PATCH] pam_lastlog2: add -lpam to Makemodule.am

If we don't add this, we don't actually link with PAM; compare the
before and after of `lib/security/pam_lastlog2.so`.

Dynamic section at offset 0x2cd8 contains 32 entries:
 Tag        Type                         Name/Value
0x0000000000000001 (NEEDED)             Shared library: [libpam.so.0]
0x0000000000000001 (NEEDED)             Shared library: [liblastlog2.so.2]
0x0000000000000001 (NEEDED)             Shared library: [libsqlite3.so]
0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
0x000000000000000e (SONAME)             Library soname: [pam_lastlog2.so]
```

This causes issues like https://github.com/NixOS/nixpkgs/issues/493934
where the library has trouble linking with PAM symbols because it is not
linked.
