enter_chroot: make sure ccache dir perms are correct

Browse Source 
For fresh sdk builds, gcc won't update and automatically see the
ccache tree for us.  So make sure the perms are sane when people
enter the chroot.  This will also automatically fix perms if/when
people manually delete the ccache dir (which sometimes happens on
the buildbots when people try to free up space).

BUG=None
TEST=`rm -rf distfiles/ccache/; cros_sdk` and see ccache dir get setup nicely
