[PATCH] scripts/min-tool-version.sh: raise minimum clang version to 15.0.0 for s390

[Heiko Carstens <hca@linux.ibm.com>]

Before version 14.0.0 llvm's integrated assembler may silently
generate corrupted code on s390. See e.g. commit e9953b729b78
("s390/boot: workaround llvm IAS bug") for further details.

While there have been workarounds applied for all known existing
locations, there is nothing that prevents that new code with
problematic patterns will be added.

Therefore raise the minimum clang version to 15.0.0. Note that llvm
commit e547b04d5b2c ("[SystemZ] Bugfix for symbolic displacements."),
which is included in 15.0.0, fixes the broken code generation.
