Bug 1545968 - Update repack_rust.py to include rust stdlib src and analysis data. r=glandium

This makes the rust toolchain artifacts contain the rust stdlib as well,
for use by searchfox. It does bring up the size of the toolchain
artifact slightly - rustc.tar.xz file for the Linux/rust 1.34 job for
example goes from 270483672 bytes to 273803148 bytes (1.23% larger) and
the equivalent android tarball goes from 230503888 to 235698736 bytes
(2.25% larger).
