init/main.c: Remove redundant space from saved_command_line

Browse Source 
There is a space at the end of extra_init_args. In the current logic,
copying extra_init_args to saved_command_line will cause extra spaces
in saved_command_line here or there. Remove the trailing space from
extra_init_args to make the string in saved_command_line look more perfect.
