time64.inc: add a comment about how to simulate Y2038 in qemu

Setting clock to 2040 causes the following ptest failures on qemux86:

Some ptests fail on qemux86-64 as well:

Note that setting the year to 2035 resolves almost all of the above,
as onl the following then fail:

qemux86:
{'python3': ['test_local_good_hostname']}
{'curl': ['test_0420']}

qemux86-64:
{'python3': ['test_local_good_hostname']}
{'curl': ['test_0420']}
