libnm: accept ipv[46].dhcp-iaid as hexstr

dhclient exports the currently used IAID in the environment as
hex string. We expose this environment in our API, so this is also
the format that NetworkManager uses.

Accept setting the ipv[46].dhcp-iaid as hex string, so that the same
format is accepted on the profile.

While at it, also accept a hex number (0x) because it is also
convenient, and this change already introduces the precedent that the
IAID string is not unique/normalized.
