Allow building without the exec() supported ...

Browse Source 
.. to satisfy restricted environment or fuzzers

We are encountering weird issues in the oss-fuzz that the file disappears during
coverage build so I assume some corpus sneaked in, that contains some commands
that end up being executed as part of the coverage run causing it randomly
failing.

The solution I propose is to build fuzzers without ability to call arbitrary
commands on the filesystem (such as `rm -rf /`) as this is not the point the
fuzzers should be testing.

This is controlled by the WITH_EXEC CMake option (enabled by default).
