selftests: mptcp: pm_nl_ctl: fix 32-bit support
commit 61d96580 upstream. When using pm_nl_ctl to validate userspace path-manager's behaviours, it was failing on 32-bit architectures ~half of the time. pm_nl_ctl was not reporting any error but the command was not doing what it was expected to do. As a result, the expected linked event was not triggered after and the test failed. This is due to the fact the token given in argument to the application was parsed as an integer with atoi(): in a 32-bit arch, if the number was bigger than INT_MAX, 2147483647 was used instead. This can simply be fixed by using strtoul() instead of atoi(). The errors have been seen "by chance" when manually looking at the results from LKFT.
