Makefile: executor: build without jump tables

When compiling SYZOS into the executor binary, the compiler often
attempts to emit a jump table, putting it into the data section of
the executor. SYZOS is unable to access that data and crashes.
To work around this, build the executor with -fno-jump-tables.

This may in theory impact the execution speed. If that happens, we'll
need to compile SYZOS as a separate translation unit.
