Linux: Add tests that check that TLS and rseq area are separate

The new test elf/tst-rseq-tls-range-4096-static reliably detected
the extra TLS allocation problem (tcb_offset was dropped from
the allocation size) on aarch64.  It also failed with a crash
in dlopen *before* the extra TLS changes, so TLS alignment with
static dlopen was already broken.
