Bug 40193: Add `AT_EMPTY_PATH` definition

`AT_EMPTY_PATH` comes with glibc 2.14. However, Debian Wheezy, which we still use for building our stable Linux bundles, comes only with glibc 2.13 resulting in an "undeclared-identifier"-error during build time.

This problem got introduced by fixing https://bugzilla.mozilla.org/show_bug.cgi?id=1660901. --- security/sandbox/linux/SandboxFilter.cpp | 4 ++++ 1 file changed, 4 insertions(+)
