net-misc/networkmanager: stop passing --with-suspend-resume=no

This causes configure to fail when USE=systemd for non-native abis.
--with-suspend-resume must be either systemd, upower, or consolekit.

Additionally, configure checks for libsystemd using pkg-config if we pass
--with-suspend-resume=systemd. There's no real need for this since the
daemon communicates with systemd using dbus. The pkg-config check is
only there to look for a new-enough version of systemd.

Passing --with-suspend-resume=consolekit does not perform any pkg-config
check. Therefore, let's use consolekit as the fallback value for the
systemd non-native abi case.
