gcc-plugins/stackleak: Ignore .noinstr.text and .entry.text
The .noinstr.text section functions may not have "current()" sanely
available. Similarly true for .entry.text, though such a check is
currently redundant. Add a check for both. In an x86_64 defconfig build,
the following functions no longer receive stackleak instrumentation:
__do_fast_syscall_32()
do_int80_syscall_32()
do_machine_check()
do_syscall_64()
exc_general_protection()
fixup_bad_iret()
