Re: [PATCH 1/6] maintenance: add get_random_minute()

I was wondering where else we call srand() within Git, and it looks like
the only other spot is in `lock_file_timeout()`.

lock_file_timeout() should be updated to match git_mkstemps_mode(),
which was taught to use the csprng_bytes() function with 47efda96
(wrapper: use a CSPRNG to generate random file names, 2022-01-17),
and this new caller may want to do so as well, perhaps?  I dunno,
but the caller then does not have to worry about "initializing it
just once".
