IOS/FS: Implement timings for older IOS versions as well
According to hwtests, older versions of IOS are slower at performing
various filesystem operations:

A quick glance at IOS9 reveals that older versions of IOS have a
simplistic implementation of memcpy that does not optimize large copies
by copying 16 bytes or 32 bytes per chunk, which makes cached reads
and writes noticeably slower -- the difference was significant enough
that the OoT speedrunning community noticed that IOS9 (the IOS that
is used for the OoT VC title) was slower.
