rseq/selftests: add -no-integrated-as for clang
Ongoing work for asm goto support from clang requires the -no-integrated-as compiler flag. This compiler flag is present in the toplevel kernel Makefile, but is not replicated for selftests. Add it specifically for the rseq selftest which requires asm goto.
