Preserve Linux capabilities when running tar, and misc fixes for mkrootfs. (#92)

Browse Source 
* Preserve Linux capabilities in various tar invocations.

Otherwise, ping as non-root will not work when using a Void image.

Don't try to umount pseudofilesystems when $rootfs is undefined.
On mktemp failure, die in the script itself, not the $( ... ) subshell.
And remove the second FATAL: from the error message.
