  ./configure --enable-arm needed for ARM events

Bug description:
  [Impact]
  The UEFI 2.6 spec added support for ARM processor errors and errors
  that have unrecognized CPER section types. rasdaemon needs to support ARM kernel trace events. To enable arm events we need to configure rasdaemon package with --enable-arm 

  [Test]
  debian/rules needs --enable-arm to enable arm events. I have a test build of the rasdaemon package in ppa:centriq-team/lp1741978-rasdaemon. I tested this on an a QDF2400 system. Here are the results for bionic, artful and xenial.
