linux-user: Fix conversion of sigevent argument to timer_create

There were a number of bugs in the conversion of the sigevent
argument to timer_create from target to host format:
 * signal number not converted from target to host
 * thread ID not copied across
 * sigev_value not copied across
 * we never unlocked the struct when we were done

Between them, these problems meant that SIGEV_THREAD_ID
timers (and the glibc-implemented SIGEV_THREAD timers which
depend on them) didn't work.

Fix these problems and clean up the code a little by pulling
the struct conversion out into its own function, in line with
how we convert various other structs. This allows the test
program in bug LP:1042388 to run.
