tests: Test readelf --debug-dump=[decoded]line with min_inst_len > 1.

This testcase tests the fix for the readelf --debug-dump=line bug fixed
in commit 40b1f18 "readelf: Fix advance_pc to use op_addr_advance, not
just op_advance."

This tests both the --debug-dump=line (readelf) implementation and the
--debug-dump=decodedline (libdw) implementation. The first fails without
the bug fix. The second was already correct.
