gnutls: upgrade 3.6.8 -> 3.6.11.1

Drop patch from 81485be19b ("gnutls: don't use HOSTTOOLS_DIR/bash as a
shell on target") as upstream now honours POSIX_SHELL when set as the
primary target shell.

(From OE-Core rev: bc487ced3be40569157fb40c99bfa68871f74744)

-Don't embed the path to the build-time POSIX shell as this will be
-$TMPDIR/hosttools/bash, which is no good on the target.

-Instead default to /bin/sh but allow it to be set in the environment.

-This isn't really upstreamable but I filed a bug at
