Downgrade NS_ERROR to NS_WARNING when failing to launch a process r=nika

It might be unrelated, but in the light of the frequent failures we see in bug 1741152: Are we sure that the assumption from bug 1737174 comment 5 still holds?

Comment 14

[Randell Jesup [:jesup] (needinfo me)]

We're seeing some issues with crashing in process startup on linux, apparently due to fd exhaustion in the main process currently (related to egl on linux). The assumption is still true, but we may be failing to start for unexpected reasons. I've downgraded this to a warning.
