[Buildroot] [PATCH 3/3] strongswan: add md4 hash algorithm option

[Martin Elshuber]

Add the option to enable the md4 hash algorithm and default it to 'no'
since this is a new option.

Since md4 is required by EAP-MSCHAPv2 it is selected by
BR2_PACKAGE_STRONGSWAN_EAP_MSCHAPV2. See
https://wiki.strongswan.org/projects/strongswan/wiki/Autoconf for
further details.
