efi/libstub/arm: Omit unneeded stripping of ksymtab/kcrctab sections
Commit f922c4abdf764 ("module: allow symbol exports to be disabled")
introduced a way to inhibit generation of kcrctab/ksymtab sections
when building ordinary kernel code to be used in a different execution
context (decompressor, EFI stub, etc)
That means we no longer have to strip those sections explicitly when
building the EFI libstub objects, so drop this from the Makefile.
