Mk/Features: Add features for fortify, zeroregs and stack autoinit.

Those 3 features for ports go along with the cooresponding features from
the basesystem (some only availabe in -current).

The options you can put into make.conf for the ports collections are:

WITH_FORTIFY=yes
    This enables mitigations of common memory safety issues, such as buffer
    overflows, by adding checks to functions like memcpy, strcpy, sprintf,
    and others when the compiler can determine the size of the destination
    buffer at compile time.

WITH_STACK_AUTOINIT=yes
    This enables a compiler specific option to automatically initialize
