Subject: [PATCH] test(e2e): disable GWP-ASan in AndroidApp to avoid Hermes
 x86_64 crash

Expo E2E jobs sometimes crash with SIGSEGV inside GWP-ASan's frame-pointer
walker (android_unsafe_frame_pointer_chase) while Hermes frees memory on a
fiber stack. This is a known Hermes V1 issue on x86_64
(facebook/hermes#1873, facebook/hermes#2225), not a memory bug in the app.
The upstream fix (73f9af39) is in Hermes 260318099.x, but Expo 58 already
ships 260318099.0.3 and still crashed, so disable GWP-ASan for the example app.
