community/cloud-utils: make -growpart subpackage depend on partx

Partx was moved out of the main util-linux and into a subpackage
therefore cloud-utils-growpart's dependency for util-linux needs
to be changed to partx instead.

Also remove cloud-utils-growpart dependency on coreutils and add
patch growpart to use a flock command-line option that is understood
by both util-linux and bosybox's flock command.

+Subject: [PATCH] cloud-utils: Make growpart call to flock work with Busybox
+
+Change growpart's to call the flock command using the short option "-x"
+rather than the long option "--exclusive" as the short option works with
+both util-linux's flock as well as Busybox's flock. This means that the
+cloud-utils-growpart package can have the util-linux dependency removed.
