compatibility by using env to resolve the correct path at runtime.

scripts: checkpatch: allow git revision selections as arguments

- The git commands `git rev-parse` and `git rev-list` were added in
version 2.19.
- `git rev-parse` can parse revision names or any revision selection and
return the corresponding git object name. This includes being able to
parse commit ranges, specific hashes, branch names, git tags, etc.
See 'https://git-scm.com/book/en/v2/Git-Tools-Revision-Selection' for
more info.
- If `git rev-parse` returns a range of git objects, `git rev-list` can
convert it into a list of commit ids.

Try to locate checkpatch.pl in typical location(s) if environment
variable CHECKPATCH is not set.
The launch script first tries to find checkpatch.pl on the path,
next it checks typical locations for linux headers, finally it
tries to locate linux sources used for OP-TEE in with QEMU.
The first match is used as the checkpatch instance to be invoked.
