add sleep_microseconds to encapsulate (u|nano)sleep
man 3 usleep: POSIX.1-2001 declares it obsolete, suggesting nanosleep(2) instead. Removed in POSIX.1-2008. we use a feature test macro to select usleep or naosleep, while debian's patch replace usleep with nanosleep. links of debian's patches is: https://salsa.debian.org/debian/runit/-/tree/master/debian/patches 0017-fix-replace-obsolete-usleep-with-nanosleep.patch
