You can use bitbake-getvar to see the default FILESPATH, but "files" next
to recipe is included by default (I prefer to use BPN directory for
slightly faster lookup - unless the files are shared between different
recipes). FILESEXTRAPATHS is usually only needed from bbappends which add
new files to SRC_URI.

For LICENSE you can use MIT and
LIC_FILES_CHKSUM =
"file://${COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420"
like many "pure-metadata" recipes in oe-core.
