Truncate user and group ids for 64 bit Linux systems (#7466)
* Truncate user and group ids

Calls to `getuid`, `getgid` and their `eid` variants fail to compile on
64bit Linux systems because the return value of the syscall is of
`usize` and needs to be truncated to fit the size of `uid_t` that is 32
bit.

Thanks to @FireFox317 for figuring this out in Zig's Discord channel!

* Add a regression test for user and group ids

* Replace @truncate with @intCast

This should be safe because `uid_t` will be 32-bit.

* Add missing import for getauxval

* Add missing package names

* Revert "Add missing import for getauxval"

This reverts commit 38f93dc89effdf657f2b81a56b96527ce4083f52.

* Skip user and group test if builtin.link_libc
