[Bug 2111585] [NEW] libstdc++.modules.json contains wrong paths

[Yehuda Bernáth]

Public bug reported:

File /usr/lib/gcc/x86_64-linux-gnu/15/libstdc++.modules.json has the following content:
{
  "version": 1,
  "revision": 1,
  "modules": [
    {
      "logical-name": "std",
      "source-path": "../include/c++/15/bits/std.cc",
      "is-std-library": true
    },
    {
      "logical-name": "std.compat",
      "source-path": "../include/c++/15/bits/std.compat.cc",
      "is-std-library": true
    }
  ]
}
But the directory /usr/lib/gcc/x86_64-linux-gnu/include does not exist.
The files std.cc and std.compat.cc are instead located in /usr/include/c++/15/bits .
