Bad suggested sysctl syntax

[j4b6ski]

sinol-make version: 1.9.9

When running sm verify --no-ingen, on some systems there's an ASAN issue "Shadow memory range interleaves with an existing memory mapping"

sinol-make then suggests:

Warning: if inwer failed due to sanitizer errors, you can either run `sudo sysctl vm.mmap_rnd_bits = 28` to fix this or disable sanitizers with the --no-fsanitize flag.

This works, but the syntax requires no spaces around the = sign.
The cmdline should be:

sudo sysctl vm.mmap_rnd_bits=28

Moreover, the same message already has the correct syntax when running sm verify with an ingen - it seems like they're two slightly different messages. This possibly might might need to be fixed in more than one place.
