[IMP] odoo: avoid warning regarding resource arg format

`struct_rusage.ru_utime` and `struct_rusage.ru_stime` are float
seconds.

`setrlimit()` takes a tuple of *integers*, and recent versions of
Python have started triggering warnings:

   DeprecationWarning: an integer is required (got type
   float). Implicit conversion to integers using __int__ is
   deprecated, and may be removed in a future version of Python.

Convert the soft cpu time limit to an integer explicitly to suppress
the warning.
