scripts/oe-selftest: remove coverage file if any coverage option is given
Coverage temporal file for sub-processing is being removed only
when the --coverage option was found. This is wrong since the
file is created when any coverage option (source, include or omit)
is given, even if --coverage is not one of them.
This patch makes sure to remove the file if any coverage option was
given.
