Currently, only custom sections can be selected by operations that use section
names, because only custom sections have explicit names (whereas known sections
have names defined by the spec and only use their indices in the binary format).
This CL makes objdopy use the spec-defined names for these sections, allowing
them to be used in operations such as dumping and removal.
This is a prerequisite for fixing

The re-use of this struct across iterations of the loop was causing
fields (specifically Name) to be incorrectly shared between multiple
sections.

Summary:
Add support for the basic section stripping (and keeping) flags for wasm:
strip with no flags, --strip-all, --strip-debug,
--only-section, --keep-section, and --only-keep-debug.
Factor section removal into a function and use a predicate chain like
the ELF implementation.

On z/OS, the following error message is not matched correctly in lit tests.
```
EDC5129I No such file or directory.
```
This patch uses a lit config substitution to check for platform specific error messages.

This is a reland of a928d127a with a one-line fix to ensure that
the wasm version number is written as little-endian (it's the only
field in all of the binary format that's not a single byte or an
LEB, but we may have to watch out more when we start handling the
linking section).
