[PATCH 10/15] build: new `--with-modem-manager-1' to check for new ModemManager1 support

[Aleksander Morgado <aleksander lanedo com>]

The new switch will run in 'auto' mode when not explicitly specified. In this
case the new ModemManager1 support will only be available if it finds libmm-glib
through pkg-config.

Other than the 'auto' mode, 'yes' and 'no' are allowed in order to specify
explicit requirements.
