Makefile: Use hg log instead of hg id --debug, which has unstable output

Also the fact that it was just broken for me - it threw debug info to stdout
("ignoring untrusted configuration option") when running 'sudo make install',
which ended up in package_revision_raw.txt, which broke the build.

HOWTOs in the "Related Pages" section.
You can also generate this documentation locally by installing
doxygen and graphviz dot, then running "make docs" in the
source tree. The documentation will be in the docs/html directory.
