tex-fonts-tlwg{,-doc}: update to 0.7.2

- Garuda has been fine-tuned by hand for balanced cubic splines
  and optimal quadratic splines.

- All families now use OS/2 Typo metrics instead of just Win/Hhea metrics.

- The OS/2 Typo metrics of each family have been normalized for equal
  line spacing on all faces, esp. regular and bold.
