musl: time64: update {IPC,MSG,SEM}_STAT definitions

This is primarily based on a small part of bminor/musl@3814333.

This also integrates bminor/musl@3c02bac, which update MSG_STAT,
SEM_STAT, SEM_STAT_ANY. These are based on the value of IPC_STAT,
however we can just use `cfg` as it is effectively the same.
