Coverity Scan Workflow Fix (#891)

Currently the Coverity Scan attempts to run on every fork that pulls
the file. This leads to anybody who pulls this file getting emails that 
their workflow failed to run when the cron job attempts to run. This
PR sets the scan to only run if the repo is FreeRTOS/FreeRTOS-Kernel.
Also, change the scan from a cron job to a job that runs on a commit
to mainline, or if triggered manually.
