doom: Bump tempstring[] size to 90 bytes.

tempstring[] is currently 80 bytes which means that the quickload
message gets truncated for long savegame names. I believe this was
always an issue (even in Vanilla?) but recent changes to use safe
string functions (commit 040ca1cfb5a3e1be7) surfaced the bug.

This fixes #1069.
