[debuginfo] Remove obsolete test_debuginfo.pl that was moved to debuginfo-tests.

[hintonda]

Summary

Now that r320495, "[debuginfo-tests] Support moving
debuginfo-tests to llvm/projects," has landed, which includes a local
copy of test_debuginfo.pl, remove the obsolete copy.

Did you check that every reference was updated to the new location?

Yes, debuginfo-test is the only places it's used. However, if an issue does comes up, we'll deal with it or revert.
