dev-lang/julia: version bump to 1.7.0

The ebuild for julia 1.7.0 with patches:
 - llvm 13 compatibility
 - libgit1.2 compatibility
 - avoid hardcoded libraries
 - do not build the library a second time
 - do not set rpaths

Some patches come from Arch Linux.

[Matthias Maier]
 - renamed patches
 - misc cleanup
