Use patched git-subtree from bjorn3/git@tqc-subtree-portable

Browse Source 
This patched has been necessary for subtree syncs from the start, but
previously it was necessary to locally install tqc's patched git
version, which hasn't been updated for quite a while. I made a small
change to allow downloading it as script without requiring an entire git
installation for the patched version.
