*: Use inline links for remaining internal references

Since f9dc90b (make link usage consistent across the specification,
2017-02-09, opencontainers#687), the official style is to only use reference-style
links for external links.  I expect the remaining three entries just
slipped through.  This commit adjusts everything found with:

  $ git grep ']: [a-z]' | grep -v http

It also fixes the underscore -> hyphen in the
glossary.md#container-namespace target and updates the capabilities
location to catch up with 5a8a779 (Move process specific settings to
process, 2016-03-02, opencontainers#329).
