maint: avoid 'const fooPtr' in all remaining places

'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can).  But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).

Fix up all remaining offenders.

* src/lxc/lxc_process.c (virLXCProcessSetupInterfaceBridged): Drop
needless const.
* src/uml/uml_driver.c (umlMonitorCommand): Use intended type.
(umlMonitorAddress): Fix fallout.
* src/xen/xm_internal.c (xenXMDomainSearchForUUID): Use intended type.
