Peter Maydell 5ea2fc84da linux-user: Sanity check clone flags 
We currently make no checks on the flags passed to the clone syscall,
which means we will not fail clone attempts which ask for features
that we can't implement. Add sanity checking of the flags to clone
(which we were already doing in the "this is a fork" path, but not
for the "this is a new thread" path), tidy up the checking in
the fork path to match it, and check that the fork case isn't trying
to specify a custom termination signal.

This is helpful in causing some LTP test cases to fail cleanly
rather than behaving bizarrely when we let the clone succeed
but didn't provide the semantics requested by the flags.
