check-package: move parts to subdirectory

Currently the check-package script uses many files in the same
directory. This commit keeps the main script in support/scripts/ and
moves the rest into a subdirectory.

The modules were previously prefixed to make it easy to identify which
script they belong to. This is no longer needed when using a
subdirectory, so the prefix is removed.

Note: if this commit is checked out and the script is run, and later on
a previous version is checked out, the file
support/scripts/checkpackagelib/__init__.pyc needs to be manually
removed to prevent Python interpreter to look for checkpackagelib
package when only the checkpackagelib module is available.
