Implement "<os firmware='efi'>" support for bhyve driver.
As there are not really lot of options, try to find
"BHYVE_UEFI.fd" firmware which is installed by the
sysutils/uefi-edk2-bhyve FreeBSD port.

If not found, just use the first found firmware
in the firmwares directory (which is configurable via
config file).

Changes from v1:

 - Fixed various leaks,
 - Re-implemented testing using opendir() mock.
