tests: avoid false failures when run in qemu user mode
* tests/filename-lineno.pl: Derive the program name that grep
will use in diagnostics, based on a suggestion from Assaf Gordon.
* tests/in-eq-out-infloop: Similar: accept an arbitrary "command_name: "
prefix on checked diagnostics, rather than requiring "grep: ".
* tests/reversed-range-endpoints: Likewise.
* tests/write-error-msg: Likewise.
