modules: Strip .llvm_addrsig sections and similar

Currently GRUB modules built with Clang or GCC have several sections
which we don't actually need or support. We already have a list of
sections to skip in genmod.sh and this patch adds the following
sections to that list (as well as a few newlines):
  - .note.gnu.property
  - .llvm*

Note that the glob there won't work without a new enough linker but the
failure is just reversion to the status quo. So, that's not a big problem.
