So far, global.usbgadget.autostart=1 from the shell was without effect,
because the variable is only evaluated once at postenvironment_initcall.
Use the new globalvar_add_bool() to allow acting on the variable being
true at any time. This is necessary for scripts that want to enable
the usbgadget autostart functionality selectively without themselves
hardcoding the particularities of what is exported.
