virbuffer: fix build on rhel-6

On rhel-6 is broken gcc that reports this warning:

util/virbuffer.c:500: error: logical '&&' with non-zero constant will
    always evaluate as true [-Wlogical-op]

Move the pragma directive before function virBufferEscapeString because
since commit aeb5262e this function uses 'strchr' too.
