This PR satisfies the OP-TEE TA's stack-guard read via the TA stack canary. Currently, the OP-TEE shim allocates a dummy TLS page to satisfy OP-TEE TA's stack-guard read (emitted by the x86_64 toolchain) even though TAs have no TLS (they are single-threaded). Instead of using such an extra page, this PR lets the stack-guard read resolve on the stack canary that the shim prepares.
