Make api.env.nss_dir relative to api.env.confdir
api.env.nss_dir is no longer hard-coded to paths.IPA_NSSDB_DIR. Instead
the path is calculated relatively to api.env.confdir. The default value
is still /etc/ipa/nssdb. The change makes it a bit easier to run
FreeIPA's API with a custom configuration directory.
