Add BR2_ROOTFS_{PRE_BUILD|POST_{BUILD|FAKEROOT|IMAGE}}_SCRIPT_ARGS

Currently, one may only specify one list of arguments that are passed to
several scripts (BR2_ROOTFS_PRE_BUILD_SCRIPT, BR2_ROOTFS_POST_BUILD_SCRIPT,
BR2_ROOTFS_POST_FAKEROOT_SCRIPT and BR2_ROOTFS_POST_IMAGE_SCRIPT_ARGS).

So one has to be careful that the arguments for these scripts do noti
collide.

To allow specifiying dedicated arguments to each type of scripts, new
config options are introduced. For backward compatibility the value of
BR2_ROOTFS_POST_SCRIPT_ARGS is still passed to the scripts. But now one
can add specific arguments from the new config option.

  - mention common args in help texts
  - slight coding style beautification
  - slight rewording in commit log
