erts: Stop using madvise(2) on Solaris
erts: Stop using madvise(2) on Solaris

inet_drv adds some arcane #defines to get SCTP working, which may
end up disabling madvise(2) locally in that file, breaking the
build in the process.

This commit disables madvise(2) altogether on Solaris as it's
far simpler than undoing the define dance in erl_mmap.h.
