Fix installation of the license file

... for ct-ng configured without --enable-local. Also, install
licenses in subdirectories of the components.

Also, ct-ng configured with --enable-local removed the scripts directory
upon `ct-ng distclean`.

Also, misspelled CT_WGET/CT_CURL variables prevented use of
`ct-ng updatetools`.

Fixes #1091.
