LOG: [flang][test] Expect a single -rpath in fveclib.f90 ArmPL check (#220969)

Fixes a `check-flang` failure on main: `Flang :: Driver/fveclib.f90`.

#220697 consolidated `tools::addArchSpecificRPath()` down to a single
call site — it was removed from `ToolChain::addFlangRTLibPath()` and
from the `-fveclib=ArmPL` block in `tools::AddLinkerInputs()`, and one
unconditional call was hoisted to the end of `AddLinkerInputs()`. A link
line can therefore emit each candidate rpath at most once, so
`CHECK-RPATH-ARMPL` fails on its second `-rpath` match:

```
flang/test/Driver/fveclib.f90:59:27: error: CHECK-RPATH-ARMPL-SAME: expected string not found in input
! CHECK-RPATH-ARMPL-SAME: "-rpath"
                          ^
```

The two matches only ever passed because `addArchSpecificRPath()` is a
pure function of the toolchain and the argument list, so the two former
call sites emitted identical paths. The test was matching a duplicate
rpath, not the separate veclib and Fortran-runtime entries that its
comment described. The arch-specific runtime directory — which is where
`flang_rt` lives — is still emitted once, so no rpath is actually lost:

```
$ flang -### -frtlib-add-rpath hello.f90
"-rpath" ".../lib/clang/24/lib/x86_64-unknown-linux-gnu"
```
