META_MODE: No need to fix the link in this case.

The exists(${DESTDIR}...) check runs with DESTDIR being blank.  When the
target runs it does have DESTDIR=${STAGE_OBJTOP} via bsd.sys.mk.  This
results in the first execution warning that the symlink is missing.  The
second run does run fine.  However, this chflags is not needed at all
for META_MODE/STAGING since we never had this path being a schg file
while using META_MODE.
