Since the code is identical when just checking if a utility is present on
the system or not, we can factorize it.

* bootstrap.conf: Remove trailing blanks.
* tests/reject-format: Define a dummy, empty variable, and use it in
here-doc to protect required trailing blanks from accidental removal.
* tests/no-newline-triggers-assert: Likewise.
* tests/preserve-c-function-names: Likewise.
* tests/create-delete: Likewise.
* tests/global-reject-files: Complete a sentence that ended in a space.
* tests/test-lib.sh: Flag tests with missing pre-requirements as
SKIPped instead of PASSed. Do not use GNU diff extensions, but
still require a diff that understands "-u".
* tests: Do not unnecessarily require GNU diff in a lot of tests.
Make the sed utility optional.
