lsb: lsb_release script incompatible with busybox head and find

Busybox implementation only supports head -1 option if ENABLE_INCLUDE_SUSv2
or ENABLE_FEATURE_FANCY_HEAD configuration options are enabled. Also the -and
option for find is only supported if ENABLE_DESKTOP configuration option is
enabled. These configuration options are not enabled in several builds, which is
why this patch is needed.
