Fix module architecture string to match Enlightenment expectations

The module architecture was incorrectly constructed as:
  linux-x86_64-0.27

But Enlightenment expects:
  linux-gnu-x86_64-0.27.1

Changes:
- Detect system ABI (gnu/musl) via features.h header check
- Use full Enlightenment version instead of just major.minor
- Correct architecture format: <system>-<abi>-<cpu>-<version>

This ensures the module installs to the correct directory that
Enlightenment will find when loading modules.

Also updated Gentoo ebuild to set S variable for correct source
directory extraction (git archives extract to 'eiwd' not 'eiwd-0.1.0').
