Mikhail Ilyin b8d43285a4 linux-user: Access correct register for get/set_tls syscalls on ARM TZ CPUs 
When support was added for TrustZone to ARM CPU emulation, we failed
to correctly update the support for the linux-user implementation of
the get/set_tls syscalls. This meant that accesses to the TPIDRURO
register via the syscalls were always using the non-secure copy of
the register even if native MRC/MCR accesses were using the secure
register. This inconsistency caused most binaries to segfault on startup
if the CPU type was explicitly set to one of the TZ-enabled ones like
cortex-a15. (The default "any" CPU doesn't have TZ enabled and so is
not affected.)

Use access_secure_reg() to determine whether we should be using
the secure or the nonsecure copy of TPIDRURO when emulating these
syscalls.
