Description: Fix the usage of DRI_DRIVER_DIR variable.
 .
 The build configuration for minigbm was lacking the dri config.
 This causes DRI_DRIVER_DIR to be undefined.
 In addition, when the dri config is properly included, the
 definition will include the quotation marks, making the
 STRINGIZE step unnecessary.
 To find the correct directory in the snap, we now prefix
 DRI_DRIVER_DIR with /snap/chromium/current/gnome-platform
