bionic: Set PTHREAD_STACK_MIN for page agnostic targets

Page size agnostic targets will have a pthread stack equals
to 65536. Page size agnostic targets will only support ARM64 arch.

For not agnostic builds, PTHREAD_STACK_MIN will remain the same.

Bug: 296907948
Test: source build/envsetup.sh
      lunch aosp_cf_arm64_phone_pgagnostic
      m

      source build/envsetup.sh
      aosp_cf_x86_64_phone-userdebug
      m
