Revert "[test] Fix win-asan symbolizer path"

This reverts commit 135576ff.

Reason for revert: V8 Win32 ASAN failures: https://build.chromium.org/p/client.v8/builders/V8%20Win32%20ASAN/builds/73

It appears these failures were lurking there already, but were hidden because of the bug this CL fixed. Opened https://crbug.com/v8/6953 about these issues.

Original change's description:
> [test] Fix win-asan symbolizer path
> 
> This makes the symbolizer path relative, as the absolute paths contain
> a drive letter + colon on windows. The colon is confused by the
> sanitizer as an option separator.
> 
> The test driver changes the cwd to the V8 root dir in each
> invocation.
>
