portage: add more config files

This allows us to override profile settings further:
- switch from ELIBC=glibc to ELIBC=bionic
- disable glib[mime] to avoid fat mime/xml deps
- disable USE=static-libs by default so we only use shared libs
- omit the charset.alias file from all packages as random GNU packages
  all want to install it (which breaks due to collisions), and the
  content is pretty pointless (maps like 2 obscure aliases)
