bpf, tls: add tls header to tools infrastructure
Andrey reported a build error for the BPF kselftest suite when compiled on
a machine which does not have tls related header bits installed natively:
test_sockmap.c:120:23: fatal error: linux/tls.h: No such file or directory
#include <linux/tls.h>
^
compilation terminated.
Fix it by adding the header to the tools include infrastructure and add
definitions such as SOL_TLS that could potentially be missing.
Fixes: e9dd904708c4 ("bpf: add tls support for testing in test_sockmap")
