[RTL-PATH]
- Fix hackish lower-casing instructions.
- Fix a DPRINT string specifier.
- Fix some string/pointer algebra.

Fixes 10 kernel32:FindFiles tests (all the "Test failed: Wrong last error. Expected
2, got 123" failures, where 123 == ERROR_INVALID_NAME).

CORE-6667 #commented "NoWine" patch committed in revision r59148.
