Do not git ignore files like /debugger/QT/moc_*.
Do not git ignore files like /debugger/QT/moc_*.

Prior to r5953, gyp_skia would generate files for QT in
debugger/QT. A line in .gitignore was added so these
files did not show up in git status. Now that the
generated files are in the out directory, the line is no
longer necessary.
