mktemp: permission denied error strip

[Devel08]

the error code should be stripped from the OS error

$ cargo run mktemp -p /
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.12s
     Running `target/debug/coreutils mktemp -p /`
mktemp: Permission denied (os error 13) at path "/tmp.haKXBI6xNU"

changes should be done here:

coreutils/src/uu/mktemp/src/mktemp.rs

Line 602 in b13ee7a

Err(e) => Err(e.into()),

Hey, I would like to work on this issue

[sylvestre]

@AnandajithS sure, please use https://docs.rs/uucore/0.9.0/uucore/error/fn.strip_errno.html for this

[Devel08]

also, GNU outputs "mktemp: failed to create file via template '/tmp.XXXXXXXXXX': Permission denied"

[Devel08]

@AnandajithS are you still working on that

[AnandajithS]

Hey @Devel08. I'm still working on this. I will have a PR ready soon
