Subject: [PATCH] [GN] Define USE_EABI_HARDFLOAT=1 when arm_float_abi=="hard".

Add this define to the config used for mksnapshot. This fixes a bug
where certain applications would fail at runtime on Chromecast.

BUG=592660
LOG=Y
Bug: internal b/27495984

Test: Formerly broken Cast apps load and run as expected.
