build: add busybox support to `time` prereq-check
Busybox time supports the GNU time '-f' syntax used by the build time logging implemented in ff6e62b288c, however the prerequisite check added only works with GNU time installed as `time` or `gtime`. As busybox is a multicall binary, the name of the symlink setup by SetupHostCommand also must be changed from `gtime` to `time` to fix the value of argv[0]. This causes a number of shells (including bash) to use their builtin impelementation of time, so the sole invocation has been changed to use `env time` to use the value found on the $PATH.
