Add a workaround to suppress specified files from Coverity Scan analysis

Re-implement temporary(?) non-functional filter to ignore specific source
code parts by Coverity Scan using "--fs-capture-search-exclude-regex" CLI
parameter of "cov-build" tool. This functionality is important to
filter out e.g. node_modules or src/tests. Instead we can remove all
specified files after we got local build results but before we send them
to Coverity server.
