rust: Cleanup commit to prepare for new bootstrap.

This commit is not atomic and is not functional by itself; this is done so to
make the next set of changes more comprehensible.

* gnu/packages/patches/rust-1.19-mrustc.patch: Delete file.
* gnu/packages/patches/rust-1.30-gdb-llvm.patch: Likewise.
* gnu/packages/patches/rust-bootstrap-stage0-test.patch: Likewise.
* gnu/local.mk (dist_patch_DATA): Un-register files.
* gnu/packages/rust.scm (mrustc): Delete variable.
(rust-1.19, rust-1.20, rust-1.21 rust-1.22, rust-1.23, rust-1.24)
(rust-1.25, rust-1.26, rust-1.27, rust-1.28, rust-1.29)
(rust-1.30): Delete variables.
(rust-1.31 through rust-1.49): Fix indentation and do other cosmetic changes.
(rust): Define as rust-1.49.
