bootstrap/README: List platforms in active use

Prompted by discussion of whether IRIX users exist on pkgsrc-users@,
list the pkgsrc platforms (foo, such that mk/platform/foo.mk exists)
according to whether they are actively maintained or not.

NB: This is merely informational, and not a deletion proposal.

+PER PLATFORM INFORMATION
+========================
+
+pkgsrc supports or has supported many operating systems (platforms).
+In general, there is a README.os for each platform that can run
+pkgsrc, explaining particular considerations.
+
+Because pgksrc contains many per-platform fixes and accommodations,
+and because the presence of those at times causes more work for
+others, we list platforms according to whether they are in active use.
+(If you feel a platform is miscategorized, send rationale to
+pkgsrc-users@.  Include a README.platform with instructions if it is
+missing and you are asserting that there are users.  Developers should
+of course feel free to make improvements.)
+
+Note that listing a platform as having no users is not a decision to
+remove it from pkgsrc; this is merely recording information that
+individual developers can use when deciding how much work is justified
+for keeping any particular accommodation.  (As always, any large-scale
+removals require a proposal and discussion on pkgsrc-users@.)
+
+Note also that pkgsrc policy is that fixes to packages, unless the
+fixes are to adjust a package to pkgsrc norms, should be filed
+upstream and the upstream tracker URL included in the patch file or
+Makefile.
+
+Platforms are listed by the filename in mk/platform, annotated by the
+README.platform here if different.
