fix(aws-serverless): Avoid minifying Module._resolveFilename in Lambda layer bundle (#12232)

FIx one of the two issues that currently cause our lambda
layer to break. When we build the lambda layer bundle we applied
minification via our terser plugin which mangles `_`-prefixed private
variables - like `Module._resolveFilename`. This patch adds the method
to the list of excluded `_`-prefixed symbols.
