[Libvir] more printf-style function checking
I had the first hunk of the following patch laying around,
but when I updated/compiled today, it triggered a warning:
virsh.c:3162: warning: format '%d' expects type 'int', but argument 6 has
type 's
ize_t'
I've fixed it by using %lu, which is more likely to be the same
width as size_t that %d, and by casting strlen's return val to
the new, expected type.

Avoid printf-style format mismatch.
* src/virsh.c (vshError): Use ATTRIBUTE_FORMAT.
(_vshStrdup): Use %lu (not %d) for strlen, and cast the strlen
return value to "unsigned long" to match the format.
