genmon_SpawnCmd() returns 0 if there is data from stdout or stderr

This patch changes genmon_SpawnCmd() to return 0 when there is data from either
stdout or stderr, otherwise -1. If there is data from both, only data from
stdout is put into the buffer.

Test by configuring genmon with a period of one second, and each of these
commands:
1. "date" should show the current date and time.
2. "date -q" should show an error message.
3. "/bin/true" should show "XXX".

This patch also includes changes from
http://bugzilla.xfce.org/show_bug.cgi?id=4036
so that this patch can be tested with "/bin/true".
