ugps: add baud rate command line option
currently, gps device baud rate is hardcoded so
ugps might not work with devices

ubus: display only available information
GPS receivers may not provide all possible data, some take more time
and some are irrelevant for some applications and are never sent by
some GPS receivers (eg. equipment found in maritime context doesn't
report elevation). Only populate attributes for which data is actually
available.
