selinux: log raw contexts as untrusted strings
These strings may come from untrusted sources (e.g. file xattrs) so they
need to be properly escaped.
Reproducer:
# setenforce 0
# touch /tmp/test
# setfattr -n security.selinux -v 'kuřecí řízek' /tmp/test
# runcon system_u:system_r:sshd_t:s0 cat /tmp/test
(look at the generated AVCs)
Actual result:
type=AVC [...] trawcon=kuřecí řízek
Expected result:
type=AVC [...] trawcon=6B75C5996563C3AD20C599C3AD7A656B
Fixes: fede148324c3 ("selinux: log invalid contexts in AVCs")
