Merge #1471

1471: unistd: Add conversion from User to libc::passwd r=asomers a=orvij

Add `From<User> for libc::passwd` trait implementation to convert a `User` into a `libc::passwd`

Implementation consumes the `User` struct, giving ownership over the internal members to the `libc::passwd` struct

Exposes the `User::gecos` field to 64-bit Android builds, since `libc::passwd::pw_gecos` is supported on those builds
