Fix recognition of PowerPC in `cpuinfo.py`

[barracuda156]

In your bug report please include:

• CPU architecture: PowerPC
• Operating System: macOS
• Python version: 3.11.10
• Version of py-cpuinfo: 9.0.0

cpuinfo omits PPC/PPC_32 in the list which breaks dependents:

In fact the arch is present just below in cpuinfo.py:

    # PPC
    elif re.match(r'^ppc32$|^prep$|^pmac$|^powermac$', arch_string_raw):
        arch = 'PPC_32'
        bits = 32

But it is broken by an earlier chunk:

# Make sure we are running on a supported system
def _check_arch():
    arch, bits = _parse_arch(DataSource.arch_string_raw)
    if not arch in ['X86_32', 'X86_64', 'ARM_7', 'ARM_8',
                   'PPC_64', 'S390X', 'MIPS_32', 'MIPS_64',
                   "RISCV_32", "RISCV_64"]:
        raise Exception("py-cpuinfo currently only works on X86 "
                        "and some ARM/PPC/S390X/MIPS/RISCV CPUs.")

Not sure how to force it recognize the arch correctly upon parsing, but this hack works:
