[Buildroot] [git commit branch/next] package/libopenssl: drop useless option for rc5

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=d7178dd432e4905cf96383e5aa316553cf30f178
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Commit a83d41867c8d (package/libopenssl: add option to enable some
features) added an option to enable rc5. However, since commit
1fff94121936 (Fixup non-x86 openssl build), dated 2002-12-30, rc5
has always been forcibly disabled in Buildroot.

Given that it was unconditionally disabled all this time, and no
one complained, it means there is virtually no-one using rc5, so we
can just drop the option.
