[PATCH] debuginfod, elfclassify: remove unnecessary header inclusion

[Saleem Abdulrasool <abdulras@google.com>]

`error.h`'s inclusion was centralised into the `system.h` header.  As
the implementation currently includes `system.h` already, the inclusion
of `error.h` is unnecessary.  This prepares for a future portability
change to allow elfutil to build with alternate libc implementations.
