[PATCH v3 3/3] libdwfl: switch to DEBUGINFOD_SONAME, remove libdebuginfod.so fallback

[Dmitry V. Levin]

Since DEBUGINFOD_SONAME is as good as ("libdebuginfod-" VERSION ".so")
for dlopen, switch to use the name which is a part of the API.

Given that DEBUGINFOD_SONAME is always available now, remove the no longer
needed fall back to dlopen of "libdebuginfod.so".
