Capabilities should not duplicate data that are obvious from our

When dealing with internal paths we don't need to worry about
whether or not suffixes are lowercase since we have full control
over them, which means we can avoid performing case-insensitive
string comparisons.

Commit a3ab6d42 changed the libvirtd profile to a named profile
but neglected to accommodate the change in the qemu profile
ptrace and signal rules. As a result, libvirtd is unable to
signal confined qemu processes and hence unable to shutdown
or destroy VMs.
Add ptrace and signal rules that reference the libvirtd profile
by name in addition to full binary path.

During storage driver backend initialization, let's save
which backends are available in the storage pool capabilities.
In order to format those, we need add a connectGetCapabilities
processor to the storageHypervisorDriver. This allows a storage
connection, such as "storage:///system" to find the API and
format the results, such as:
virsh -c storage:///system capabilities
<capabilities>
<pool>
<enum name='type'>
<value>dir</value>
<value>fs</value>
<value>netfs</value>
<value>logical</value>
