Angus Lees 5a00350935 Add support for Linux capabilities
This change adds a new `capabilities` kwarg to PrivContext, which
specifies the Linux capabilities to retain on the privileged side of
this context.  This allows the privileged daemon to be run as root but
with restricted permissions, or as not-root but still with some limited
superpowers.

A new `capabilities` config option is added to the context config
section that overrides the default capabilities for that context.  It is
expected that this will rarely be used.

Note that there is intentionally no way to specify "I want all
capabilities".
