[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=d17c0a348fc10897d86e0e96aa98be5ac88d6fdd
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

4c20d9f2b removed FEATURE_FLOAT_SLEEP option, thus since then there are
only two variants.

Fixes: 4c20d9f2b ("extend fractional duration support to "top -d N.N" and "timeout"")
