sys/targets: use a different SYZ_DATA_OFFSET for 32-bit FreeBSD (#1809)
* sys/targets: use a different SYZ_DATA_OFFSET for 32-bit FreeBSD
It seems that the value used on all platforms (512 << 20) does
not work on 32-bit FreeBSD when using the clang tools.
Try (256 << 20) instead.
* sys/targets: add comment why a non-default value is needed
