package/c-libraries: need linux-headers

Now that we check that a target package in the _DEPENDENCIES of another
package has to be enabled in config, all target packages must have a
kconfig symbol.

Add a Kconfig symbol for linux-headers, and select it from the packages
that depends on it (C libraries).

Also remove the now-misleading comments "for legal-info" from the C
libraries.
