Borrow value instead of moving in FsPath::from()

When accepting a value of AsRef<Utf8CStr> in FsPath::from(), the
existing code will move a value of Utf8CStrBufArr, creating a reference
that lives longer than the borrowing value, causing undefined behavior.

The issue is only visible on release builds, as more advanced
optimizations will be more aggressive re-using the stack of variables
that no longer lives.

Fix #7408
