Update some elements using tar source
Those elements were not switched to git_tag because they either:
- had no official git source.
- would cause cyclic dependency if built from git.
- were not straight forward to to build from git due to complex bootstrap script.
Two elements cannot be upgraded easily: gettext 0.20.1 which breaks compilation of p11-kit. And librsvg 2.45.7 which does not compile.
