Rollup merge of #21964 - semarie:openbsd-env, r=alexcrichton
- add `_SC_GETPW_R_SIZE_MAX` constant - declare `struct passwd` - convert `load_self` to `current_exe` Note: OpenBSD don't provide system function to return a valuable Path for `env::current_exe`. The implementation is currently based on the value of `argv[0]`, which couldn't be used when executable is called via PATH.
