Get rid of CT_LIBC_FILE, remove useless CT_MakeAbsolutePath.

CT_LIBC_FILE:
- that one was not easy, as it had sneaked into CT_ExtractAndPatch
- which in turn made CT_ExtractAndPatch have references to C library addons
- which in turn relieved the C library _extract functions from doing their own job
- which in turn imposed some nasty tricks in CT_ExtractAndPatch
- which in turn made life easier for the DUMA _get and _extract functions
- which unveiled some bizare behavior for pushd and popd:
- if using smthg ike: 'pushd foo |bar':
- the directory is *neither* changed
- *nor* is it pushed onto the stack
- which made popd fail

CT_MakeAbsolutePath:
- used only to make CT_LOCAL_TARBALLS_DIR canonical
- which is ((almost) useless:
- hopefully, the user entered a full path already
- if it's not the case, too bad...
