revert 7f18485: improve uefi detection mechanism
Make is_uefi_supported() only check for /sys/firmware/efi as
get_efi_partition() will detect a missing ESP or an invalid
partition scheme. Stop using get_efi_partition() inside
is_uefi_supported() as the former is eventually called in every
UEFI related code.
UEFI supports both MBR and GPT as partition schemes and this is
a required change to handle the particular case of Windows not
being able to boot UEFI from a MBR partition scheme.
