[PATCH] debuginfod: fix compilation on platforms without <error.h>

["Érico Nogueira" <ericonr@disroot.org>]

From: Érico Nogueira <erico.erc@gmail.com>

"system.h" only declares the error() function, so it needs to be in an
'extern "C"' block, otherwise linking fails.

Since we are here, use quotes for "system.h" header, since it's a local
header, not a system one.
