fetch: SRC_URI parameter "subdir" does not work for local files

Check if the 'subdir' parameter exists and assign it to 'destdir' so that
files are copied in ${WORKDIR}/destdir. This fixes urls that are of the form
file://a;subdir=b.

fetch: Extend testing of subdir unpack parameter and fix

This fixes urls of the form file://some/path/file;subdir=b. It also
adds in a couple of tests so we now tests these corner cases.
