[sanitizer_common][test] Disable sanitizer_coverage_trace_pc_guard.cp…

…p etc. on SPARC When enabling ASan testing on SPARC as per PR llvm#107405, two tests `FAIL`: ``` SanitizerCommon-asan-sparc-SunOS :: sanitizer_coverage_trace_pc_guard-dso.cpp SanitizerCommon-asan-sparc-SunOS :: sanitizer_coverage_trace_pc_guard.cpp ``` The issue is the same in both cases: ``` WARNING: No coverage file for projects/compiler-rt/test/sanitizer_common/asan-sparc-SunOS/Output/sanitizer_coverage_trace_pc_guard.cpp.tmp WARNING: No coverage file for sanitizer_coverage_trace_pc_guard.cpp.tmp.22766.sancov ERROR: No valid coverage files given. ``` Checking the file with `sancov -print` reveals `Wrong magic: 4294967090`. There seems to be an endianess bug somewhere, since the tests are already disabled on other big-endian targets. This patch matches this. Tested on `sparcv9-sun-solaris2.11`.
