[sanitizer_common] Make sanitizer_linux.cpp kernel_stat* handling Lin…

…ux-specific

fcd6bd5 broke the Solaris/sparcv9 buildbot:

compiler-rt/lib/sanitizer_common/sanitizer_linux.cpp:39:14: fatal error: 'asm/unistd.h' file not found
   39 | #    include <asm/unistd.h>
      |              ^~~~~~~~~~~~~~

That section should have been Linux-specific in the first place, which is what this patch does.

Tested on sparcv9-sun-solaris2.11.

(cherry picked from commit 16e9bb9)

This was originally part of the merge PR #101236, but was missed when merging the original PR #101012 instead.
Missing in 19.1.0-rc3 caused the Solaris/sparcv9 build to break, so this should be in -final.

test-release.sh build with this patch applied locally currently running for final verification.

[rorth]

The Solaris/sparcv9 build just completed successfully: no regressions relative to rc2.
