debuginfod: Fracture tests/run-debuginfod-find.sh into specific tests

tests/run-debuginfod-find.sh was a massive test script with many broadly
varying tests. This caused the test script to fail when any number of
things went wrong and because of its intertwined nature, detecting the
source of a failure could be difficult. The size of the test script
also meant many unrelated tests were run making the testing process
unnecessarily lengthy.

This patch fractures tests/run-debuginfod-find.sh into smaller, more
manageable individual test script files. This ensures that when failure
occurs, a programmer can easily determine where their patch went
wrong. It also allows programmers to specify exactly which tests to
run, making testing more efficient. Redundancies are also reduced by
placing code in tests/debuginfod-subr.sh.
