Kevin Lubick 805acda3f3 [fuzzer] Remove GL from (now-Vulkan) build 
The fuzzer runs against the Vulkan version of Swiftshader.
There are no libGL.so (etc) on the fuzz runtime, so we
want to avoid linking against those.

The GL code that is #ifdef'd out is still necessary to
avoid timeouts on TSAN with our NVIDIA jobs.
https://skia-review.googlesource.com/c/skia/+/502638

Procedure for testing this locally (and iterating):
  1. In oss-fuzz checkout, run
     `python infra/helper.py shell skia`
     to pull up local interactive version of Docker
     fuzzer build image.
  2. Run `compile` in fuzzer shell. Stop after
     the swiftshader compiles and is copied into /out
     with Ctrl + C.
  3. Comment out the swiftshader compilation part [1]
     (no need to re-do this when modifying Skia code).
     `apt-get install nano -y`
     `nano ../build.sh`
  4. Make change to Skia repo using normal methods.
  5. Run the following in the Skia repo
     `git diff origin main > foo.patch`
     Copy the patch into the Docker shell using Ctrl+C
     and nano.
  6. Apply the patch inside the Docker shell
     `git apply foo.patch`
     and re-compile (which should skip right to
     building the fuzzer libs)
     `compile`
  7. Repeat 4-7 or make small changes directly in
     the Docker shell via nano.
  8. When compilation and link succeeds, run
     `ldd /out/api_mock_gpu_canvas`
     to verify GL and friends were not dynamically linked.
