tracing: Handle CC_FLAGS_FTRACE more accurately
CC_FLAGS_FTRACE is exported and later used to remove ftrace relevant build flags from files which should be built without ftrace support. For that reason add -mfentry to CC_FLAGS_FTRACE as well. That fixes a problem with vdso32 build on s390, where -mfentry could not be used together with -m31 flag. At the same time flags like -pg and -mfentry are not relevant for asm files, so avoid adding them to KBUILD_AFLAGS. Introduce CC_FLAGS_USING instead of CC_USING_FENTRY to collect -DCC_USING_FENTRY (and future alike) which are relevant for both KBUILD_CFLAGS and KBUILD_AFLAGS.
