Disable HWASAN on ifunc resolvers.
We can't have HWASAN enabled in these resolvers because they
may be called before HWASAN is initialized.
We were previously getting away with HWASAN being enabled on these
functions because ANDROID_EXPERIMENTAL_MTE was not defined, which
let the compiler simplify away any HWASAN instrumentation in the
resolvers. But with this build flag enabled (which is currently the
case in FVP, and eventually everywhere once the MTE kernel patches
land) the resolvers end up containing an HWASAN instrumented load of
the _hwcap2 field.
