meson: using local copy ldscript when local copy crt0 be used for SBAT

When the system crt0 for aaarch64 is not new enough for SBAT. The
efi/meson.build script will use local copy crt0 instead:

  efi/meson.build:87: WARNING: Cannot find SBAT section in
  /usr/lib64/crt0-efi-aarch64.S, using local copy

In this case, the ld of efi/fwup.so will be failed because missing
symbols:

Using local copy ldscript when local copy crt0 be used for SBAT, then
this fail can be fixed.
