[ Merge of http://go/wvgerrit/153121 ]
`run_oemcrypto_fuzz_tests` script was disabled while OPK was
transitioning between v16 and v17. Now that OPK is v17, the
fuzz tests can be re-enabled.
Some targets could not be built due to a missing header file.
`oemcrypto/ref/src/cppbor.cpp` was updated to include the missing
header.
