Adjust verify.h licence
Adjust verify.h licence

verify.h can be licensed as LGPLv2+ rather than GPLv3, see
http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=modules/verify;h=5216ce890dac58e596a27341e31258e5d6c0d702;hb=HEAD

A verify.h file with the appropriate licence can be generated from a
gnulib clone using:
gnulib-tool --lgpl=2 --import verify

This will fail if the 'verify' module is not licensed under a compatible
license.
