libpayload: Make Kconfig bools use IS_ENABLED()

This will make the code work with the different styles
    of Kconfig (emit unset bools vs don't emit unset bools)

Roughly, the patch does this, and a little bit of fixing up:

perl -pi -e 's,ifdef (CONFIG_LP_.+?)\b,if IS_ENABLED($1),g' `find . -name *.[ch]`
    perl -pi -e 's,ifndef (CONFIG_LP_.+?)\b,if !IS_ENABLED($1),g' `find . -name *.[ch]`
