init: make the command-line rewrite optional
When launched as PID 1 and after parsing its arguments, init wipes all all of them except argv[0] and rewrites argv[0] to contain only "init", so that its command-line appears solely as "init" in tools such as ps. This patch adds the FEATURE_INIT_MODIFY_CMDLINE which, if set to n, will make init preserve all its arguments including argv[0], be they parsed or ignored. The original command-line used to launch init can then be retrieved in /proc/1/cmdline on Linux, for example.
