Subject: [PATCH 2/2] perf buildid-cache: Add test for 16-byte build-id

tests/shell/buildid.sh added an ELF executable with an MD5 build-id to
the perf debug cache but did not check whether the object was printed
by a subsequent call to "perf buildid-cache -l". It was being omitted
from the list.

A previous commit fixed the bug that left it out of the list. This adds
a test for it.
