external/firebird: Drop -fno-rtti from sanitizer builds HEADmaster

Until now, at least Clang silently drops -fsanitize=vptr (which needs RTTI, and
which is by default included in -fsanitize=undefined) from -fsanitize=undefined,
that's how external/firebird (which uses -fno-rtti) worked for now with
-fsanitize=undefined.  However, Clang is planing to break -fsanitize=vptr out of
-fsanitize=undefined (see
<https://discourse.llvm.org/t/rfc-remove-vptr-from-undefined/83830> "[RFC]
Remove `vptr` from `undefined`"), so to be prepared for that I started to do my
local ASan/UBSan build with an explicit -fsanitize=vptr already.  Which thus
started to cause

> clang++: error: invalid argument '-fsanitize=vptr' not allowed with '-fno-rtti'

But there appears to be no good reason to do such instrumented builds with
-fno-rtti anyway.
