[lld] [lld][test] filecheck typo fixes (PR #93471)

The arm-thumb-branch-rangethunk.s needs a couple of updates:
* The test is calibrated to .text starting at 0x20000 which due to page size changes no longer holds. I've added -Ttext=0x20000 to force this.
* I've updated the disassembly as short thunks are now used.

Feel free to add this to your patch.

It should be:
```
// REQUIRES: arm
// RUN: llvm-mc -arm-add-build-attributes -filetype=obj -triple=thumbv7a-none-linux-gnueabi %s -o %t
// RUN: llvm-mc -arm-add-build-attributes -filetype=obj -triple=thumbv7a-none-linux-gnueabi %S/Inputs/far-arm-thumb-abs.s -o %tfar

// RUN: llvm-objdump --no-show-raw-insn -d %t2 | FileCheck %s
