--ignorefile silently fails if the file in question does not exist

[mdirkse]

Description

If an ignore file is specified using the --ignorefile flag and that file doesn't exist Trivy does not produce any warning or error as a result of the misconfiguration.

Desired Behavior

If I configure a --ignorefile flag and the file it poitns to doesn't exist I expect Trivy to fail with a message that the file is missing or at the very least produce a clearly visible warning about the problem.

Actual Behavior

The missing file is silently ignored and no indication is given of the misconfiguration.

Reproduction Steps

1. Create an empty directory and, inside, create an empty main.tf file
2. Run trivy as follows from inside the directory: trivy config --ignorefile non-existant.yaml . --debug
3. Marvel as it totally ignores the fact that the ignorefile doesn't actually exist
