[Buildroot] [PATCH] libqmi: udev and qmi-over-mbim are optional

[Aleksander Morgado <aleksander@aleksander.es>]

Don't always build without udev, as qmi-firmware-update would be very
very limited in that case. Instead, make it optional: if there is udev
support in the setup, require libgudev and configure using --with-udev
explicitly; otherwise just --without-udev.

Also, add the qmi-over-mbim feature as optional, and require libmbim
if we're building with it enabled.
