[PATCH] readelf: Try to continue after encountering bogus ELF Note data.

[Mark Wielaard <mark@klomp.org>]

There might be other sections or segments with ELF Notes that are
readable. Also adjust error message depending on whether or not we
actually got any data for the ELF Note segment or section.
