        src/usr.sbin/perfused: perfused.c

Log Message:
Survive if filesystem installs a signal handler

We tested for signal(3) to return 0 for success, which is incorrect:
signal(3) returns the previous handler. Success should be tested as
!= SIG_ERR, otherwise we fail when a signal handler was previously
installed by perfused(8) parrent process, which happens to be the
FUSE filesystem.
