cpio: fix boot with dynamic /dev Devtmpfs doesn't get automounted by the kernel when an initramfs is used. Since cpio archives are used almost exclusively as an initramfs, the same fix should be applied to it as for the initramfs. Cfr. commit 424888e47431db738f5f9b3c6392435bfce7a842 and 10a130f91e5b947e2d2558443ff09b1686eac273.

fs/common: Create initial console device A /dev/console node must be present in rootfs when the Linux kernel boots otherwise the kernel will print the following warning: "Warning: unable to open an initial console" This is because when we use an initramfs the /dev directory is not populated at this point. This can cause problems when a program (e.g ldso with early debugging enabled) opens a standard file descriptor for read/write before these descriptors are actually created by the init process later on.

fs/common.mk: delay evaluation of variables This makes things easier to understand and more consistent with the pkg-infra. For example, it removes the need for '$$@' in the CMD variables of fs//.mk. It also makes it possible to update the variables later, e.g. in the package override file. It also makes sure that the date will be recorded correctly in Yann E. Morin's patch that logs the MESSAGE macros to a file. The fs//.mk must be updated as well because the '$@' shouldn't be quoted anymore in the CMD variables or the hooks. The $(eval ...) for the dependencies is redundant, because the $(ROOTFS_TARGET) variable is already eval'd. Note that it is only redundant if the evaluation of the uses of the variable is also delayed.
