[OE-core] [PATCH v3] image-prelink: remove hardcoded path assumptions, don't generate cache file

[Phil Blundell]

Pass -N option to prelink so that no cache file is generated (obviates need for deleting it afterwards).
Use symbolic names, ${sysconfdir} et al., rather than hardcoded paths. 
Pass explicit -c option to prelink in case ${sysconfdir} and ${sysconfdir_native} are different.
