Tools failure on linux when ptiagent install fails

[Matthew Stuart]

Issue:

Usually during an OS upgrade and kernels got rebuilt / installed the next time it comes up the ptiagent --install command fails with the message:

Symptom:

`The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

ptiagent-cmd --install

Stdout from the command:

Stderr from the command:

modprobe: FATAL: Module prl_tg not found in directory /lib/modules/5.4.0-126-generic`

Proposed resolution:

If the ptiagent install fails cascade down to reinstalling the tools from the system ISO
