package/pppd: bump version to 2.5.0

Removed all patches, they are now included in this release.
Added other patches fixing errors.

Removed option BR2_PACKAGE_PPPD_RADIUS, upstream build system, now auto-
conf-based, does not support disabling the radius plugin.

Removed BR2_PACKAGE_PPPD_OVERWRITE_RESOLV_CONF, upstream now defaults to
/etc, quoting README:
"Note that if you have built and installed previous versions of this
package and you want to continue having configuration and TDB files in
/etc/ppp, you will need to use the --sysconfdir option to ./configure."

Switched build system to autoconf, added optional systemd support.

Added configure option to enable multilink support which now defaults to
false but was enabled before:
