libsanitizer: Fix up build against latest kernel headers

Browse Source 
The Linux kernel recently removed the linux/scc.h header, so gcc (both
16.1-rc2 and trunk) fails to build e.g. on Fedora rawhide now.

The following patch cherry picks a recent upstream fix for this, the macros
defined in that header haven't been really used since 2013-ish.

2026-04-29  Jakub Jelinek  <jakub@redhat.com>

	* sanitizer_common/sanitizer_platform_limits_posix.cpp: Cherry picked
	from LLVM commit 3dc4fd6dd41100f051a63642f449b16324389c96.
