tools: add support for library names other than libxen*

All Xen libraries but one (libxlutil) are named libxen...

Add support in the generic library build framework for that different
naming by adding another indirection layer. For a library
LIB_PREFIX_<lib> can be set in tools/libs/uselibs.mk. The default is
"xen", assuming that all libraries are starting with "lib".

For now don't expand this support to stubdoms, as it isn't needed
there yet.
