Set glibc versions for standalone installers

[charliermarsh]

Summary

Per Discord, it sounds like cargo-dist will assume that 2.31 is our minimum glibc version, since we're building our own binaries. (You can confirm this by looking at uv-installer.sh.)

cargo-dist now supports specifying a glibc override for each target: https://opensource.axo.dev/cargo-dist/book/reference/config.html#min-glibc-version. This is great, since we use 2.17 everywhere, but 2.28 for ARM.

Ran dist build -a global --tag=v0.5.11 locally, and verified that target/distrib/uv-installer.sh contains the right versions, e.g.:

"armv7-unknown-linux-gnueabihf")
    _archive="uv-armv7-unknown-linux-gnueabihf.tar.gz"
    if ! check_glibc "2" "17"; then
        _archive=""
    fi
    if [ -n "$_archive" ]; then
        echo "$_archive"
        return 0
    fi
    _archive="uv-armv7-unknown-linux-musleabihf.tar.gz"
    if [ -n "$_archive" ]; then
        echo "$_archive"
        return 0
    fi
    ;;
...
"aarch64-unknown-linux-gnu")
    _archive="uv-aarch64-unknown-linux-gnu.tar.gz"
    if ! check_glibc "2" "28"; then
        _archive=""
    fi
    if [ -n "$_archive" ]; then
        echo "$_archive"
        return 0
    fi
    _archive="uv-aarch64-unknown-linux-musl.tar.gz"
    if [ -n "$_archive" ]; then
        echo "$_archive"
        return 0
    fi
    ;;
