bootstrap/install.rs: support a nonexistent prefix in x.py install

Browse Source 
PR #49778 introduced fs::canonicalize() which fails for a nonexistent path.
This is a surprise for someone used to GNU Autotools' configure which can create any necessary intermediate directories in prefix.

This change makes it run fs::create_dir_all() before canonicalize().
