build: coverage: work around lcov 1.12 bug by using absolute paths for info files

In case a warning gets printed from lcov some internal function changes the dir
to / and thus fails to create files in the given file later on. Using an
absolute path here is a workaround to avoid this problem. The fix is in lcoc
already but not yet in any release so we better keep this around here.
