support/scripts/apply-patches: fallback $TAR to `tar`
Commit f77d698f83b230f7efcb7d28af3aacfa9589cc89 changed apply-patches to
use $TAR instead of `tar`, but did not define a fallback if $TAR is not
defined. This results in an error when calling apply-patches.sh from
outside Buildroot's Makefile. Our team uses this script to setup local
checkouts of Buildroot package's with patches for development.
