tests/tcg/multiarch: enable additional linux-test tests
Un-comment the remaining tests.
I removed the itimer value tests because I'm fairly sure a re-arming
timer will always have a different value in it when you grab it.
I've also fixed up the clone thread flags as QEMU will only allow a
clone to use flags which match glibc. However the test is still racey
so it remains disabled by default - it can be run by passing any
additional parameters on the command line.
