bitbake: fetch/git: add support for removing arbitrary revs for shallow

In certain cases, it's valuable to be able to exert more control over what
history is removed, beyond srcrev+depth. As one example, you can remove most
of the upstream kernel history from a kernel repository, keeping predominently
the non-publically-accessible content. If the repository is private, the
history in that repo couldn't be restored via `git fetch --unshallow`, but
upstream history could be.

Example usage:

    # Remove only these revs, not at a particular depth
    BB_GIT_SHALLOW_DEPTH_pn-linux-foo = "0"
    BB_GIT_SHALLOW_REVS_pn-linux-foo = "v4.1"
