Fixes gpscat to avoid the possibly missing select.poll().

Although poll() is generally preferred to select() in C code, in
Python, select.poll is considered OS-dependent, and is missing in some
Python versions, notably in some OSX cases.  Since gpscat is not a
performance-critical application, simply using the older but more
portable select.select is preferable to some fancier scheme using
different methods on different OSes.

TESTED:
Ran gpscat on OSX with all supported Python versions.
