checksec fails on statically linked binaries

[fefe17]

For example, RELRO and RUNPATH do not apply to static binaries, and stack canaries and fortify checks don't work because there are no external symbols you could detect.

I think it would make sense to change the display as to not cause confusion and false positives.

#194 includes a partial fix for static binaries. it should report N/A for Runpath and rpath. Still a few things remaining to fix but some of it is in there
