dev-php/symfony-filesystem: new version 3.2.8.

This new version adds a tiny patch to annotate the one test that
requires network access. Afterwards, we are able to enable the test
suite and skip the network test. The test suite passes, so I've
removed the RESTRICT=test that we had. The patch is reflected
in upstream (symfony/symfony) pull request 22630.

Another small improvement is to spell out the files and directories to
be installed, rather than using "." (the whole directory). This avoids
installing composer.json and some other junk to the PHP include
directory.
