webkitgtk: reduce size of -dbg package

Unless DEBUG_BUILD is enabled, pass -g1 to massively reduce the size of
the debug symbols (4.3GB to 700M at time of writing):

  Level 1 produces minimal information, enough for making backtraces in
  parts of the program that you don't plan to debug. This includes
  descriptions of functions and external variables, and line number
  tables, but no information about local variables.

This makes the sstate objects a lot more manageable, and packaging
faster.  On my machine:

  PKG          TASK                 ABSDIFF  RELDIFF  WALLTIME1 -> WALLTIME2
  webkitgtk    do_compile           -613.8s   -21.7%    2823.3s -> 2209.5s
  webkitgtk    do_package           -143.4s   -53.6%     267.7s -> 124.3s
  webkitgtk    do_install            -93.7s   -60.1%     156.0s -> 62.3s
  webkitgtk    do_populate_sysroot   -51.6s   -86.4%      59.7s -> 8.1s

Cumulative walltime:
  -892.9s    -26.5%    56:06.3 (3366.3s) -> 41:13.4 (2473.4s)
