libext2fs: include sys/time.h for gettimeofday()

Building on my glibc-2.15 system hits a warning:
	gen_bitmap64.c: In function 'ext2fs_alloc_generic_bmap':
	gen_bitmap64.c:127:2: warning: implicit declaration of function
		'gettimeofday' [-Wimplicit-function-declaration]

Include sys/time.h if it's available for the prototype.
