wic: get rid of using wic-tools

At the moment, when building images with IMAGE_FSTYPES=wic one ends up
depending on wic-tools and thus syslinux and grub-efi even when not
using those at all. Ideally, building an image with wic should only
build the tools and components really needed.

The problem is that "wic-tools" is needed also for the manual
invocations of wic, in which case everything that might be needed has to
be built in advance.

Replaced dependency on wic-tools with dependency to a much shorter set
of tools that wic uses almost for any image: 'parted', 'gptfdisk',
'dosfstools' and 'mtools'.
