build fails due to embedded library

build fails due to

E: squeekboard: embedded-library usr/bin/squeekboard: libyaml

i guess this is wanted for the moment so s.th. like in debian/squeekboard.lintian-overrides (untested) should do the trick:

squeekboard binary: embedded-library usr/bin/squeekboard: libyaml

see https://lintian.debian.org/manual/section-2.4.html . this can be tested locally by running lintian on the binary - it'd do an mr but i don't want to pull in the cargo mess.
