functions (ValidateBuildRoot): require canonical RPM_BUILD_ROOT

Browse Source 
Some scripts like lib.req rely on the fact that RPM_BUILD_ROOT
should not end with trailing slashes or something.  Other
scripts like find-package explicitly assume that RPM_BUILD_ROOT
can be relocated within filesystem; they use something like
"real_buildroot" variables.  The code gets complicated,
fragile, and error-prone.

Therefore, guys, hereby I FORBID non-canonical RPM_BUILD_ROOT path.
Note that RPM_BUILD_ROOT actually does not have to exist.
This is another problem...
