[PATCH] unit_test: check_clamav: skip .rar files if there is no rar support

From: Sebastian Andrzej Siewior <[email protected]>

Otherwise the testsuite will fail because we failed to detect the
infected files hidden in .rar files.
This patch removes .rar files from beeing scanned and decreases the
number of files (currently we have two .rar files) which will be
found/tested.
