tests/run-make: Update list of statically linked musl targets

All of the tier 3 targets in the list now link dynamically by default (except `mips64el-unknown-linux-muslabi64`, I apparently overlooked that one in my PR that changed this).

Adjust the list of targets expected to link statically accordingly.

See also #144410, which changed these targets.

Target by target:
- `mips64-unknown-linux-musl`: this target does not exist AFAICT
- `mips64-unknown-linux-muslabi64`: updated in the linked PR
- `powerpc-unknown-linux-musl`: updated in the linked PR
- `powerpc-unknown-linux-muslspe`: updated in the linked PR
- `powerpc64-unknown-linux-musl`: updated in the linked PR
- `riscv32gc-unknown-linux-musl`: updated in the linked PR
- `s390x-unknown-linux-musl`: updated in the linked PR
- `thumbv7neon-unknown-linux-musleabihf`: updated in the linked PR
