[Peter Seiderer <ps.report@gmx.net>]

- add optional host-freetype dependency

Fixes:

  Command: .../host/bin/python2 .../build/qt5webengine-5.15.2/src/3rdparty/chromium/build/config/linux/pkg-config.py -p .../build/qt5webengine-5.15.2/host-bin/host-pkg-config freetype2
  Returned 1.
  stderr:

  Package freetype2 was not found in the pkg-config search path.
  Perhaps you should add the directory containing `freetype2.pc'
  to the PKG_CONFIG_PATH environment variable
  Package 'freetype2', required by 'virtual:world', not found
  Could not run pkg-config.

  See //build/linux/BUILD.gn:24:3: whence it was called.
    pkg_config("freetype_from_pkgconfig") {
    ^--------------------------------------
  See //build/config/freetype/BUILD.gn:10:24: which caused the file to be included.
      public_configs = [ "//build/linux:freetype_from_pkgconfig" ]
                         ^--------------------------------------
