objtool: Remove "ANNOTATE_NOENDBR on ENDBR" warning 

This warning isn't very useful: why would you put ANNOTATE_NOENDBR on
ENDBR, and if you did, what's the harm?

And thus far it's only found one non-bug, where the
'__end_entry_SYSENTER_compat' label happens to land on the ENDBR from
entry_SYSCALL_compat:

  vmlinux.o: warning: objtool: entry_SYSCALL_compat+0x0: ANNOTATE_NOENDBR on ENDBR

.. which is fine.  Just remove the warning.
