testlib: Detect distribution name/release for blacklisting tests

Add possibility to blacklist distributions using the syntax:
"<productType>" and "<productType>-<productVersion>".

productType and productVersion are the values returned by
QSysInfo::productType() and QSysInfo::productVersion() (in lower case).
