Tools: Test: Audio: Add possibility to test ASRC with src_test.m

The same tests can be applied for ASRC in sychronous mode. This
patch allows to pass component name as last argument. Use it
this way:

src_test(32, 32, 44100, 48000, 0, 1, 'asrc');

or

src_test(32, 32, 44100, 48000, 0, 1, 'src');
src_test(32, 32, 44100, 48000, 0, 1);

To run ASRC or SRC. See "help src_test" output for all
test options.
