Optimize filesystem::path::parent_path()

Parsing a complete string is more efficient than appending each
component one-by-one.

Backport from mainline
2019-05-29  Jonathan Wakely  <jwakely@redhat.com>

* src/c++17/fs_path.cc (path::parent_path()): Create whole path at
once instead of building it iteratively.
