coredump,catalog: give better notice when a core file is truncated
coredump had code to check if copy_bytes() hit the max_bytes limit, and refuse further processing in that case. But in 84ee0960443, the return convention for copy_bytes() was changed from -EFBIG to 1 for the case when the limit is hit, so the condition check in coredump couldn't ever trigger. But it seems that *do* want to process such truncated cores [1]. So change the code to detect truncation properly, but instead of returning an error, give a nice log entry. [1] https://github.com/systemd/systemd/issues/3883#issuecomment-239106337 Should fix (or at least alleviate) #3883.

+The process had more memory mapped than the configured maximum for processing
+and storage by systemd-coredump(8). Only the first @SIZE_LIMIT@ bytes were
+saved. This core might still be usable, but various tools like gdb(1) will warn
+about the file being truncated.
