remove %RUNAS% implementation: It was documented at all. The concept can be good but the implementation is really ugly...

Respect state of ss_flags_init flags: the dance 66-stop -u -> 66-disable -> 66-enable -> 66-start of a classic service produce an error at s6-svstatus read due of an initialized service at /run/66/scandir/*. Remove old function ss_resolve_pack,ss_resolve_add_uint32.

The check of the symlink can return true even if lstat return -1, so be sure to only pass if the lstat return 0 and the symlink check return true

allows @runas field to be on format uid:gid,uid:,:gid or uid whereas uid and gid is the name of user and the name of the group respectively

add %RUNAS% feature: allow to choose the place where write the s6-setuidgid command at execute field
