Update entitlements to support installation of extensions providing u…

…nsigned libraries

This commit sets "com.apple.security.cs.disable-library-validation" to true
and is intended to prevent error like the following reported
after installing extension like SlicerHeart or after (re-)installing
python package providing unsigned compiled python module (e.g numpy).

  /path/to/Slicer-5.0.2.app/Contents/Extensions-30822/SlicerHeart/lib/Slicer-5.0/qt-loadable-modules/libqSlicerKretzFileReaderModule.dylib:
    code signature in (/path/to/Slicer-5.0.2.app/Contents/Extensions-30822/SlicerHeart/lib/Slicer-5.0/qt-loadable-modules/libqSlicerKretzFileReaderModule.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.)
