package/nodejs: fixup qemu dependencies

Commit 1facb09b94bf806b301868539185c0ff9ddffee2 ("package/nodejs:
build host-nodejs only if we're installing modules with NPM") forgot
to account for the dependency on Qemu. Now that nodejs no longer
depends on host-nodejs, but needs host-qemu, we need to make sure that
nodejs selects the relevant BR2_PACKAGE_HOST_QEMU options.

So this patch:

 - Drops the dependency of BR2_PACKAGE_NODEJS_ARCH_SUPPORTS on
   BR2_PACKAGE_QEMU_ARCH_SUPPORTS_TARGET, which was incorrect: we
   don't care about running Qemu on the target. We care about
   host-qemu supporting the emulation of the target architecture,
   which is what BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS is for.

 - Adds the dependency to the relevant BR2_PACKAGE_HOST_QEMU options
   to BR2_PACKAGE_NODEJS, so that host-qemu is built with the
   appropriate features needed to build the target nodejs.

 - Removes the qemu related dependencies from host-nodejs, which does
   not need Qemu at all.

Without this change the build of nodejs without npm enabled is broken
as the host-qemu that gets built does not have all the features that
are needed. There are no autobuild failures at this point, however.
