rust: Switch to the memmap2-rs crate
https://github.com/RazrFalcon/memmap2-rs
This is a fork of the original memmap crate which appears to be unmaintained:
https://github.com/danburkert/memmap-rs/issues/90
This fork is the most popular according to https://crates.io/keywords/mmap

Subrepository paths shouldn't be expanded, but we fail to handle them
properly. Any local repository paths are expanded.

Test tilde
----------
The leading tilde may be expanded to $HOME, but it can be a valid subrepo
path in theory. However, we want to prohibit it as there might be unsafe
handling of such paths.
