Do not require .ko suffix on kpatch load

Right now "kpatch list" will list "loaded patch modules" without .ko
suffix.  However, if one tries to load the patch with the name as it
appears in "kpatch list", it will not work because it lacks the .ko
filename suffix.

This commit modifies the kpatch list output to consistently not show the
.ko suffix in both the "loaded patch modules" and "installed patch
modules" sections, and allows the .ko suffix to be omitted for "kpatch
load"

Fixes #371
