[ClamAV] Disable mempool at compile time (#3304)
ClamAV's mempool feature uses mmap to improve performance for some
memory allocations. As currently implemented, on systems that support
mmap's MAP_ANONYMOUS flag, fmaps are backed by mmap'd memory.
Valgrind and ASan can't track mmap-backed memory, though, so it's more
difficult to track down fmap-related memory errors.
The changes in this commit to clamav's build script should disable mmap
usage, and hopefully allow oss-fuzz to catch more bugs.
