sstate.bbclass: fix issue while handling long sstate filenames

When moving to python3, divison using '/' now returns float instead of
an integer. In upstream commit b8025e972081b70960ffcbcbe43a7118041556a1
sstate filenames longer than the limit are changed to just include
necessary info + 3 fields just for information. The space left over
after the necessary info is divided into 3 for each of the fields.
Using '//' instead to do the division to solve the following error
message:

avail = (254 - len(hash + "_" + taskname + extension) -
len(components[0]) - len(components[1]) - len(components[5]) -
len(components[6]) - 7) / 3
    >        components[2] = components[2][:avail]
             components[3] = components[3][:avail]
TypeError: slice indices must be integers or None or have an __index__
