Use php stream in exif fuzzer
...
This has the main benefit that we don't go through the
realpath cache, which will cause leak checking to be
disabled.

Reduce oniguruma limits in fuzzing sapi
...
The defaults are fairly conservative and may still take quite a
bit to match a single expression. Reduce them by a factor of 10x
to speed up fuzzing.

Make fuzzing sapi i386 compatible
...
* Avoid an unnecessary -lstdc++ dependency. It's not going to be
used in the end anyway, and is an unnecessary hassle to set up.
* Use $LIB_FUZZING_ENGINE instead of hardcoding -lFuzzingEngine.

Limit max length for parser fuzzer
...
We're getting some very large inputs (~500KB) on OSS-Fuzz, which
slot down performance a lot. Let's try limiting this, starting
with a still fairly large value of 64KB.
Also remove the max_execution_time limit, so that slow test cases
cause a genuine libfuzzer timeout and we may investigate them.
