Disable sysroot for ASan GN builds
The ASan runtime requires libstdc++, and the version on the bots is older
than the version in the sysroot, so ASan-built sel_ldr from the sysroot
won't run. For now we disable the sysroot (this matches the SCons build)
but the term fix would be to just use GN's libcxx build.
