elf.rb: avoid corrupted elf files

Browse Source 
Some elf files like unittest files or memory dumps may not be completely
readable by readelf.

Readelf will fail after the following message:
readelf: Warning: possibly corrupt ELF header - it has a non-zero program header offset, but no program headers

This patches avoid these files when there is a non zero offset but no
program headers
