Tweak fz_try/catch to fix overflow case.

In the current code, when we hit the fz_try(), we check to see
if we are about to overflow the exception stack. If we are,
we throw. This does NOT throw to the fz_catch following the
try, but rather to the enclosing fz_always/fz_catch blocks.

This can cause leaks, as it's very hard to code correctly.

It would be a far nicer behaviour to have a failure in fz_try()
cause us to throw to the immediately following fz_always/fz_catch.

This commit achieves that.
