Fixes #7427

[sylvestre]

can we centralize the string somewhere ? to be able to update it in a single place

GNU testsuite comparison:

GNU test failed: tests/misc/tee. tests/misc/tee is passing on 'main'. Maybe you have to rebase?
Skip an intermittent issue tests/timeout/timeout (fails in this run but passes in the 'main' branch)

Ok, I found a solution: I moved the string to .cargo/config.toml and added our own crate_version macro to uucore.

FYI this breaks out-of-tree builds, where .cargo/config.toml does not get used. I'll send a fix.
E.g.:

$ mkdir test-uutils
test-uutils$ cargo build --manifest-path=../coreutils/Cargo.toml
...
error: environment variable `PROJECT_NAME_FOR_VERSION_STRING` not defined at compile time
   --> src/uu/base32/src/base_common.rs:107:18
    |
107 |         .version(uucore::crate_version!())
...
