BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=2365

This patch is to fix a build tool regression issue which was introduced
by commit 8ddec24dea74.

compiler output message includes localized string.
So build failed when code decode the stdout/stderr byte arrays.
The cause of the build failed is that Commit 8ddec24dea74
removed "errors='ignore'".

The build tool does not need to deal with localized string,
so we need to add "errors='ignore'".

this function is only invoked for structure PCDs.
Build failed if structurePcd is used in platform dsc file.
The patch is going to fixed this issue
