[lld][test] Fix file cleanup in aarch64-build-attributes.s (#164396)

This test seems to have taken the lit documentation at its word:
https://llvm.org/docs/CommandGuide/lit.html#substitutions

"%t temporary file name unique to the test"

%t is in fact the **path** of a file. As suggested by the line below
that describing %basename_t.

This test (I assume) assumed it was just the filename itself and so left
a layout of:
```
$ tree tools/lld/test/
tools/lld/test/
├── CMakeFiles
├── ELF
│   └── Output
│       ├── aarch64-build-attributes.s.tmp
│       │   ├── pauth-bti-gcs.s
│       │   └── pauth-bti-pac.s
│       ├── aarch64-build-attributes.s.tmp.merged.o
│       ├── aarch64-build-attributes.s.tmp1.o
│       ├── aarch64-build-attributes.s.tmp2.o
│       └── aarch64-build-attributes.s.tmp3.o
├── Unit
│   └── lit.site.cfg.py
├── cmake_install.cmake
└── lit.site.cfg.py
```

Note how the 2 .s files are in the temp dir but the .o files are not.
This is fine, it works, but it's going to cost someone time to unpick
when this test actually does fail.

To fix this, remove %t from all the temp file names so they are created
in the temp dir, which is cleaned before each run.

New layout:
```
$ tree tools/lld/test/
tools/lld/test/

├── ELF

│       └── aarch64-build-attributes.s.tmp
│           ├── 1.o

│           ├── 3.o
│           ├── merged.o

│           └── pauth-bti-pac.s
