rust-common: Fix for target definitions returning 'NoneType' for arm

[YOCTO #14742]

The build shows below error while building for arm machines.
Exception: TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
Detailed error info :

Steps to reproduce:
1. Set MACHINE ?= "qemuarm" in local.conf & add 'TOOLCHAIN_HOST_TASK:append = " packagegroup-rust-cross-canadian-${MACHINE}"'
2. bitbake core-image-minimal -cpopulate_sdk

Complete Error:

Below are the local variables from rust_gen_target function for arm and
aarch64 targets. Refer below, the tspec varibles for 'arm' generated with NoneType.

(a) Locals at rust_gen_target for arm::
tspec['data-layout'] =  None, Type of tspec['data-layout'] =  <class 'NoneType'>
tspec['data-layout'] =  None, Type of tspec['data-layout'] =  <class 'NoneType'>
DEBUG: Python function do_rust_gen_targets finished
(b) Locals at rust_gen_target  for aarch64::
tspec['data-layout'] =  aarch64-unknown-linux-gnu, Type of tspec['data-layout'] =  <class 'str'>
tspec['max-atomic-width'] =  128, Type of tspec['max-atomic-width'] =  <class 'int'>

Reason for changing arm-eabi to arm: The earlier changes introduced this bug, so reverting the change 'arm-eabi' to 'arm' fixed the issue.
