efi/libstub: Drop __pure getter for efi_system_table
The practice of using __pure getter functions to access global
variables in the EFI stub dates back to the time when we had to
carefully prevent GOT entries from being emitted, because we
could not rely on the toolchain to do this for us.
Today, we use the hidden visibility pragma for all EFI stub source
files, which now all live in the same subdirectory, and we apply a
sanity check on the objects, so we can get rid of these getter
functions and simply refer to global data objects directly.
Start with efi_system_table(), and convert it into a global variable.
While at it, make it a pointer-to-const, because we can.
