Make the test more hash-agnostic by renaming variables from "sha1" to
some variation of "oid" or "packid". Also, replace the regex,
`[0-9a-f]\{40\}` with `$OID_REGEX`.

A better name for "incrpackid" (incremental pack-id) might have been
just "packid". However, later in the test suite, we have other uses of
"packid". Although the scopes of these variables don't conflict, a
future developer may think that commit_and_pack() and
test_has_duplicate_object() are semantically related somehow since they
share the same variable name. Give them distinct names so that it's
clear these uses are unrelated.
