Subject: [PATCH] META_MODE: Follow-up r287865 and define CCACHE_DIR as
 realpath'd.

Filemon(4) will record paths as they are seen, not as fully resolved.  make(1)
will take the .MAKE.META.IGNORE_PATHS values and resolve them.  This creates
a discrepancy if CCACHE_DIR is a symlink.  Fix this by ensuring it is
resolved for its actual usage.
