[INTERNAL] TestSuite: add ConcatFilter / synchronize LessFilter

The ConcatFilter takes care to concatenate resources like
sap-ui-core.js, sap-ui-core-nojQuery.js and sap-ui-debug.js on the fly
once they are requested.

The LessFilter needs to be synchronized to avoid timing issues when
accessing resources which are compiled at the time a request happens.

Adopted line delimiters to UNIX.
