package/ripgrep: convert to cargo infrastructure

This commit converts the ripgrep package to the cargo
infrastructure. This causes the vendoring mechanism to kick in, which
changes the contents of the tarball. To avoid a clash on the hash, we
change the version of ripgrep to the Git commit hash matching the
13.0.0 tag, so there are no functional changes, but the tarball name
is different.
