Revert "patchelf: use 0.13.x on aarch64+musl"

This reverts commit e22d0b49a9553861cdaee9f71b37db4baf2bb992.

No longer needed now that we have an up-to-date
aarch64-unknown-linux-musl bootstrap.

Since the original commit, patchelf_0_14 was renamed to
patchelfStable. There's no longer any need for it to have a name
other than "patchelf", but I've kept "patchelfStable" around as an
alias in case anybody's using it.
