T6674: move patches to "package/<package_name>" subfolder

This prevents the accidental applying of a patch to multiple source directories
defined in package.toml.

Example FRR:
Package consits of build instructions for libyang, rtrlib and frr itself.
Previously patches in frr/patches folder got applied to libyang, rtrlib and frr
which made no sense and could also fail a build.
