Fix more Freetype build feature dependencies in app_server
PackageInstaller: Increase install type description height

 * In case the scroll bar needs to appear, it had not enough room.
app_server: Don't offset first glyph with additional spacing

Untested, but should be correct... will test in a minute.
HaikuDepot, text stuff: Removed work around.

 * The extra glyph or white space offset no longer needs to be removed from
   the first glyph.
