util: virerror: Don't use stack'd buffers in error report helpers

This was (probably) a relict from times when we cared about OOM
conditions and the possibility to report the error. Nowadays it doesn't
make sense as virRaiseErrorFull will do an allocated copy of the strings
and also concatenate the error message prefix with the detail which
doesn't guarantee that the result will be less than 1024 chars.
