readelf: Skip trying to uncompress sections without a name
When combining eu-readelf -z with -x or -p to dump the data or strings
in an (corrupted ELF) unnamed numbered section eu-readelf could crash
trying to check whether the section name starts with .zdebug. Fix this
by skipping sections without a name.
* src/readelf.c (dump_data_section): Don't try to gnu decompress a
section without a name.
(print_string_section): Likewise.
