Since the introduction of fuzz testing, there has never been a problem
found because of a failure of a file in the fuzzer seed corpus. As the
fuzzer has found problems, they have been added to the test suite, and
that should be adequate to exercise the fuzzers in the tesing
environment as well as providing adequate regression testing.
Removing these original files shaves many minutes off the builds in CI.
When making resources indirect in from_dr, the code was using the
wrong owning QPDF, forgetting that from_dr had already been copied
using CopyForeignObject.
It's detected in QPDFWriter instead of at parse time because I can't
figure out how to construct a test case in a reasonable time. This
commit moves the fuzz file into the regular test suite for a QTC
coverage case.
