OPNA2608andRaito Bezarius ce3e9e81b0 meson: Fix Meson CPU names for powerpc CPUs
Nixpkgs expects the `builtin.currentSystem` for POWER CPUs to be:

`powerpc[64][le]-linux`

But using `host_machine.cpu_family()` for the CPU part of the system
string on POWER produces this instead:

`ppc[64]-linux`

So evaluating Nixpkgs errors out on:

`error: Unknown CPU type: ppc64`

To fix this, change
`ppc` -> `powerpc`
`ppc64` -> `powerpc64`
and append `le` if `host_machine.endian() == 'little'`.

I can't actually test this on hardware rn due to hitting a kernel bug
on the host system when linking big things[1], but the approach here
is similar to how it was fixed in cppnix[2][3], so it *should* be fine.
