master a2842a1: Don't use symbolic links in the test resource directory.

[Philipp Stephani]

branch: master
commit a2842a11728336fc8110eedb5176ecfbe71bbc79
Author: Philipp Stephani <phst@google.com>
Commit: Philipp Stephani <phst@google.com>

    Don't use symbolic links in the test resource directory.
    
    This doesn't work on Windows.  Instead, use the EMACS_TEST_DIRECTORY
    environment variable to find the BPF files.
    
    * test/src/emacs-tests.el (emacs-tests--lib-src): New constant.
    (emacs-tests/seccomp/allows-stdout)
    (emacs-tests/seccomp/forbids-subprocess)
    (emacs-tests/bwrap/allows-stdout): Use it.
