BaseTools: Warn user the file not found issue instead of break build.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2770

The Trim.py would break the build process when the file not found
issue occures, however sometimes we do not care about this issue.
This patch changes the error with warning in order to solve this
kind of break.
