tests: Filter out extra files from codecov reports

wpa_cli and hostapd_cli are not currently tested for code coverage, so
filter the files specific to those components away from the code
coverage reports. *_module_tests.c are not included in normal builds, so
drop them as well. In addition, drop the system header file (byteswap.h)
that gets somehow unnecessarily included in the reports for couple of
lines.
