runit @2.1.2: error: implicit declaration of function 'execve' is invalid in C99

[fgatherlet (fgatherlet)]

I cannot install runit. Maybe because of C99 implicit declaration check.

In 841ca477424cac003a602291b54e27cca1379d0a/macports-ports (master):

runit: Fix implicit declaration of functions

Closes: #61680

Also add size to checksums, use MacPorts flags, add universal variant,
don't compress manpages manually because MacPorts does so automatically,
and use notes instead of post-install ui_msg.
