Julia Kreger 81137d4045 Return false for MBR bootloader check on UEFI machines
Somewhat common are dual boot images that have both a MBR loader
and the contents required for a UEFI boot, as largely the pointer
to where to begin reading the rest of the boot loader occurs in
the first few hundred bytes on disk which redirects the disk to
begin reading from a known address.

This goes sideways on UEFI machines where this method of booting
is not recognized nor supported. Thus we need to return false when
we encounter this state.

Fixes an issue with deployment ramdisks running in UEFI boot mode where
dual-boot images may cause the logic to prematurely exit before UEFI
parameters can be updated. Internal checks for a BIOS bootloader will
always return ``False`` now when the machine is in UEFI mode.
