Drop the 0001-include-sys-types.h-explicitly-for-getting-caddr_t-d.patch
patch as it was fixed in this version[1].
This switches the source from pypi to git (github) as the new version
wasn't published yet.
Lastly, we use the LICENSE.txt file for LIC_FILES_CHKSUM so we don't
have to deal with context lines in the README file.
