bindexplib: Revert support for constants symbols

Revert the main logic change of commit v3.9.0-rc1~192^2 (bindexplib: fix
constants symbols export, 2017-04-26) and its test case.  Unfortunately
some constants may be provided by multiple object files with different
`@...` suffixes, leading to ambiguous references.  Revert support
pending further investigation.

Fixes: #17045
