[compiler-rt] Disable some unittests on windows that rely on shell command

Summary:
These unittests are not running on windows because they are using incorrect commands.
They were not failing on 32-bits because there is a requirement: asan-64-bits.

```
$ "nm" "C:\src\llvm\ninja64\projects\compiler-rt\test\asan\X86_64WindowsConfig\TestCases\Output\no_asan_gen_globals.c.tmp.exe"
# command stderr:
'nm': command not found
error: command failed with exit status: 127
```

```
$ "rm" "-rf" "C:\src\llvm\ninja64\projects\compiler-rt\test\asan\X86_64WindowsConfig\TestCases\Output/coverage-tracing"
$ "mkdir" "C:\src\llvm\ninja64\projects\compiler-rt\test\asan\X86_64WindowsConfig\TestCases\Output/coverage-tracing"
$ "A=x"
# command stderr:
'A=x': command not found
error: command failed with exit status: 127
```


```
$ "DIR=C:\src\llvm\ninja64\projects\compiler-rt\test\asan\X86_64WindowsConfig\TestCases\Output/coverage-order-pcs"
# command stderr:
'DIR=C:\\src\\llvm\\ninja64\\projects\\compiler-rt\\test\\asan\\X86_64WindowsConfig\\TestCases\\Output/coverage-order-pcs': command not found
error: command failed with exit status: 127
```
