readelf: print_attributes (-A) robustify and handle non-gnu attributes.

print_attributes wasn't robust against empty or broken attribute sections.
It also only handled GNU attributes. But the arm backend contains some
none-GNU attributes. The difference is in how to handle the tag arguments.

Adds a new test run-readelf-A.sh for both gnu (ppc32) and non-gnu (arm)
attributes.
