[OE-core] [PATCH V3] ruby: Use arm32 for coroutines on 32bit-arm

[Khem Raj]

in 2.7 [2] ruby enabled ucontext for coroutines on arm32 but it does not
work for musl since it uses glibc specific functions e.g.
getcontext/swapcontext/swapcontext also see [1]

This patch reverts back to using arm32 implementation for coroutines on
arm
