procrank/procmem fail on 0-length page mappings

procrank prints messages such as:
warning: could not read usage for 279
and does not include that pid in its table of results

procmem segfaults when run against that process

The problem is the 0-length page map at the top of the stack:

beb39000-beb39000 rw-p 00000000 00:00 0
beb39000-beb5a000 rw-p 00000000 00:00 0          [stack]

This patch changes the code to skip over that 0-length mapping when calculating
memory usage

ext4_utils: Fix bad merge of EMMC wipe suppression

The order of the modules in the Makefile changed.

The Makefile items for eMMC wipe suppression should be
in the sections for target static and dynamic
libext4_utils.  These were the first two modules in the
file previously, but no longer are.

Move the eMMC wipe configuration handling to the proper
modules.
