s390/purgatory: disable branch profiling
[ Upstream commit 03c5c83b70dca3729a3eb488e668e5044bd9a5ea ]
Avoid linker error for randomly generated config file that
has CONFIG_BRANCH_PROFILE_NONE enabled and make it similar
to riscv, x86 and also to commit 4bf3ec384edf ("s390: disable
branch profiling for vdso").
