[llvm-symbolizer][test] Simplify test input reading

This change migrates most llvm-symbolizer tests away from reading input
via stdin and instead using --obj + positional arguments for the file
and addresses respectively, which makes the tests easier to read.

One exception is the test test/tools/llvm-symbolizer/pdb/pdb.test, which
was doing some manipulation on the input addresses. This patch
simplifies this somewhat, but it still reads from stdin.

More changes to follow to simplify/break-up other tests.
