tracelib: resource forks not handled correctly

[Ionic (Mihai Moldovan)]

tracelib is not handling resource forks correctly.

Example from python27's destroot phase:

For python.exe, denying access to the resource fork leads to a build failure.

The /.vol/.../ path should be resolved to the real one and checks performed against that.

VolFS paths are correctly handled as of r127033, the Python build in trace mode is fixed with r127024.

Dealing with resource forks (i.e. stripping /..namedfork/* from the path if present) still needs to be done.

[neverpanic (Clemens Lang)]

Resource forks should be handled correctly as of r127673.
