capabilities: add (back) dummy support for KEEPCAPS

The dummy module is used by folk that run security conscious code(!?).  A
feature of such code (for example, dhclient) is that it tries to operate
with minimum privilege (dropping unneeded capabilities).  While the dummy
module doesn't restrict code execution based on capability state, the user
code expects the kernel to appear to support it.  This patch adds back
faked support for the PR_SET_KEEPCAPS etc., calls - making the kernel
behave as before 2.6.26.
