Add ATTRIBUTE_PRINTF to trace_start_error

Browse Source 
clang complains that the fmt passed to vwarning in trace_start_error is
not a literal.  This looks like a fair warning, which can be removed by
adding ATTRIBUTE_PRINTF to the declaration of trace_start_error.

gdb/ChangeLog:

	* nat/fork-inferior.h (trace_start_error): Add ATTRIBUTE_PRINTF.
