pkgtools/pkglint: update to 19.3.4

Changes since 19.3.3:

In cases where the conditions for including buildlink3.mk files differ
between the package itself and its own buildlink3.mk file, explain how
to determine PKG_OPTIONS for dependencies.

Don't issue wrong warnings in options.mk files when the options are
handled in a .for loop.
