Kernel: Create all kernel processes before enabling boot profiling

Process created performance events for kernel processes are only ever
emitted for the kernel processes that exist when profiling is enabled.
Any new kernel processes created after profiling is enabled will not
have corresponding process created performance events, so all kernel
processes should be created before enabling profiling.

NetworkTask was the only kernel process being created after enabling
profiling, so we now just create it before enabling profiling. This
fixes an issue where Profiler was failing to parse boot profiles as a
result of NetworkTask not having a process created event.
