rt-tests: bump to v0.94

All of the rt-tests patches that OE has been carrying have been
upstreamed or superceded by changes in the v0.94 release.

Adjust SRC_URI to point to canonical upstream git repo, instead of a
development tree.

There was a notable change upstream that required slight reworking of
the recipe.  rt-tests now joins other kbuild-inspired projects by making
use of a CROSS_COMPILE flag to indicate the compiler prefix.

Previously TOOLCHAIN_OPTIONS were conveyed via $CC directly, however,
this does not work with CROSS_COMPILE.  Workaround this by both
specifying CROSS_COMPILE, and feeding the rt-tests build system the
proper $(HOST_CC_ARCH)$(TOOLCHAIN_OPTIONS) via $CFLAGS.

-childinfo_t is a union that contains both signed (error) and unsigned
-(threadid) members. Thus a large threadid could appear as a negative error
-value, which will cause unexpected failures.
-
-childinfo_t should be changed to a struct, but it could potentially affect the
-performance. So we keep it as a union but only check error against -1. There is
-still a chance of false alarm but it's small.
