minor doc fix

[Bart Veer <bartv@ecoscentric.com>]

Current docs for the remote protocol file I/O extension state that a
struct timeval is 8 bytes. It is actually 12, a 4-byte time_t tv_sec
and an 8-byte long tv_usec. It is not clear why tv_usec was made a
long rather than an int, but that is what has been implemented in
remote_fileio_to_fio_timeval() and hence what current server
implementations expect.

	* gdb.texinfo: gettimeofday() involves a 12-byte transfer, not 8
	bytes.
