busybox: enable fractional sleep arguments 

Fractional durations (e.g. 0.5s) for the sleep command are useful and
not terribly uncommon in practice, especially in scripts associated
with test cases (e.g. mdadm, lttng-tools).  Enable FEATURE_FLOAT_SLEEP
by default in order to avoid having to patch every instance of a
script using a fractional sleep.

The busybox binary gains a few hundred bytes in text (armv5e shown):

$ size -x busybox.nosuid.{before,after}
   text	   data	    bss	    dec	    hex	filename
0x89382	  0x71d	 0x2250	 572655	  8bcef	busybox.nosuid.before
0x8954e	  0x721	 0x2250	 573119	  8bebf	busybox.nosuid.after
