libs/git: Actually patch recursively

Previously the only way patching would work is if for every target
there existed a corresponding directory under $project/$PATCHES, e.g:

"./libreboot update coreboot x200 8MiB corebootfb grub"

would require the "grub" directory and its parents:

"projects/coreboot/patches/x200/8MiB/corebootfb/grub"

Now you only need target-specific patch directories if you need them;
I believe this was the intended behavior.

Superfluous quotes were removed for readability.
