main/postmarketos-base: remove initstepslew from chrony configuration (!838)
Comment out the initstepslew line in /etc/chrony/chrony.conf.
initstepslew can delay booting while chrony sets the time. The
makestep 1 -1 line in the configuration also causes chrony to step
the time (whenever the offset is greater than 1s), making
initstepslew redundant.
