p2p: Skip some tests if xattr support is not available.
This is needed because some builders still lack xattr / fallocate
support despite being updated to Precise. Also gracefully handle lack
of fallocate(2) support since this feature is not always available
either.
BUG=chromium:298397
TEST=Remounted the filesystem holding my chroot with nouser_xattr
(e.g. 'mount -oremount,nouser_xattr /ssd') and unit tests pass with
the newly added warning.
