[PATCH 2/2] Fix test/os to work on Solaris

[Alan Coopersmith]

Due to bad decisions made decades ago at AT&T, on SVR4 OS'es the signal()
function resets the signal handler before calling the signal handler
(equivalent to sigaction flag SA_RESETHAND).  This is why the X server
has a OsSignal() helper function in os/utils.c that uses the portable
POSIX sigaction function to provide BSD/Linux semantics in a signal()
style API, so we switch to use that in this test case, allowing it to
pass on Solaris.
