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. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

-+# 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.
