[OE-core][PATCH] qemuarm: check serial consoles vs /proc/consoles

[Trevor Gamblin]

Note that this patch affects qemuarm AND qemuarm64.

When booting a VM and during operation, the following message
periodically appears:

INIT: Id "hvc0" respawning too fast: disabled for 5 minutes

This is because hvc0 is specified in SERIAL_CONSOLES in qemuarm.conf
and qemuarm64.conf, but it is not in /proc/consoles and
SERIAL_CONSOLES_CHECK is not specified, leaving getty to attempt to
enable hvc0. Add SERIAL_CONSOLES_CHECK to both conf files so that
hvc0 isn't enabled if it hasn't been set there or in local.conf.
