efi_selftest: remove redundant function efi_st_memcmp()

Function memcmp() is available in efi_freestanding.c. So we do not remove a
further implementation.

Replace all usages of efi_st_memcmp() by memcmp().

efi_selftest: expect boot services data for fdt

In a previous patch the memory type used for the FDT has been changed to
boot services data. We have to adjust the test.

Correct an incorrect comment. The tested services are boot services.

efi_selftest: check fdt is marked as runtime data

Check that the memory area containing the device tree is marked as runtime
data.

Update the Python test to pass ${fdtcontroladdr} to bootefi.

Update the description of the Python test.
