Subject: [PATCH] fix(mlock): add AIX support and tighten unavail build
 constraints

mlock_unix.go: add aix to supported platforms (mlockall(2) and MCL_CURRENT/
MCL_FUTURE are available on AIX, and golang.org/x/sys/unix exports Mlockall
for aix/ppc64). Also add the modern //go:build tag alongside the legacy
// +build comment.

mlock_unavail.go: switch from enumerating unsupported platforms to negating
supported ones, so new platforms (like aix) are covered automatically once
added to mlock_unix.go rather than requiring a separate change here.
