Disable `rpmalloc`

Building with `rpmalloc` fails with error due to the use of
reserved identifiers in the library. This appears to be due
to `-Wreserved-identifier` parameter enabled in recent clang
versions.

Disable `rpmalloc` as it prevents landing fixes for other
platforms. This will be re-enabled when the compilation can
be fixed or disabled.
