Cleanup cramfs package declaration.

Cramfs still passes the device table to mkcramfs, which is irrelevant
now with fakeroot, remove this behaviour and the associated patch.

-+# When building a target filesystem, it is desirable to not have to
-+# become root and then run 'mknod' a thousand times.  Using a device 
-+# table you can create device nodes and directories "on the fly".
-+#
-+# This is a sample device table file for use with mkcramfs.  You can
-+# do all sorts of interesting things with a device table file.  For
-+# example, if you want to adjust the permissions on a particular file
-+# you can just add an entry like:
-+#   /sbin/foobar	f	2755	0	0	-	-	-	-	-
-+# and (assuming the file /sbin/foobar exists) it will be made setuid
-+# root (regardless of what its permissions are on the host filesystem.
-+# Furthermore, you can use a single table entry to create a many device
-+# minors.  For example, if I wanted to create /dev/hda and /dev/hda[0-15]
-+# I could just use the following two table entries:
-+#   /dev/hda	b	640	0	0	3	0	0	0	-
-+#   /dev/hda	b	640	0	0	3	1	1	1	15
-+# 
-+# Device table entries take the form of:
-+# <name>    <type>	<mode>	<uid>	<gid>	<major>	<minor>	<start>	<inc>	<count>
-+# where name is the file name,  type can be one of: 
-+#	f	A regular file
-+#	d	Directory
-+#	c	Character special device file
-+#	b	Block special device file
-+#	p	Fifo (named pipe)
-+# uid is the user id for the target file, gid is the group id for the
-+# target file.  The rest of the entries (major, minor, etc) apply only 
-+# to device special files.
-+
-+# Have fun
