package/pppd: disable for musl toolchains

For the same reason as for ipsec-tools [1], disable pppd for musl
toolchains.
It also include <sys/cdefs.h> which is not provided by musl [2].

This fixes a compilation error with musl libc because of undeclared
__P and missing sys/cdefs.h include.

Propagate the dependency to network-manager and rp-pppoe
packages.
