Hi,

This patch is a second fix for PR d/87866, as dmd front-end function
FileName::canonicalName could be called during the semantic pass of
import("file") expressions, so still requires that realpath() be
redefined.

Bootstrapped and ran D2 testsuite on x86_64-linux-gnu.

Committed to trunk as r269619.
