SubjectMakefile.build: make KBUILD_SYMTYPES work again
Date
commit 37a8d9f67f18de1e2cbc7387311ce22d4dbff518 tried to combine some
duplicate code and accidentally broke how KBUILD_SYMTYPES worked

This fixes the code to match the original intention by the author who
originally added the code I believe.

The fixes include:
- removing extra whitespaces in the if-statements
- moving the if-statement from around the -r to the -T
- adding a second arg to cmd_gensymtypes to simplify the options passed
to genksyms.

Tested by instrumenting genksyms and seeing what options were passed in
during a make, KBUILD_SYMTYPES make, and when a foo.symref was created.

Everything compiled and looked ok.
