configure: Fix unexpanded ALSA_DATA_DIR

When no --with-alsadatadir is given, configure scripts takes
$datadir/alsa as the default location, while it's expanded to
$prefix/data/alsa.  Although ALSA_DATA_DIR is set via
AC_DEFINE_UNQUOTED(), this expands only $alsadatadir itself and not
about the $prefix in the content.  For resolving this, we need to do
eval twice.
