PR libstdc++/91012 fixfilesystem_error::what() string
When I refactored the filesystem_error code I changed it to only use the
constructor parameter in the what() string, instead of the string
returned by system_error::what(). That meant it no longer included the
description of the error_code that system_error adds. This restores the
previous behaivour, as encouraged by the standard ("Implementations
should include the system_error::what() string and the pathnames of
path1 and path2 in the native format in the returned string").
PR libstdc++/91012
* src/c++17/fs_path.cc (filesystem_error::_Impl): Use a string_view
for the what_arg parameters.
(filesystem_error::filesystem_error): Pass system_error::what() to
the _Impl constructor.
* testsuite/27_io/filesystem/filesystem_error/cons.cc: Ensure that
filesystem_error::what() contains system_error::what().
