check_orderfile: Also check symbols with dot in name

It turns out that when verifying symbol order, all symbols with '.' in
their name are ignored. This is probably coming from the days when the
orderfile was listing the order of _sections_ instead of _symbols_ (as
it currently does). A number of sections in the orderfile was in the
form of '.text.foo' or '.text.hot.foo' after the 'orderfile patching'
step.

These days adding those prefixes is not necessary. Regardless of the
section the function appears in, its symbol will remain unchanged, and
LLD would be able to find this section by the symbol's name.

However, with some more aggressive ThinLTO on arm64 a large number of
symbols get renamed by appending a unique suffix, like so:

```
foo.llvm.2659584300663683305
```

Include functions like that in order verification.
