[PATCH openbmc-build-scripts] use glibc 2.22 to work around assembler error

[OpenBMC Patches]

@shenki after our buildroot was seemingly re-worked from upstream master, initramfs builds have been failing[1] on openpower.xyz.

```
03:57:49 ../sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S: Assembler messages:
03:57:49 ../sysdeps/unix/sysv/linux/powerpc/powerpc64/setcontext.S:367: Error: junk at end of line: `1,0'
```

They work fine if I build with glibc 2.22 instead of 2.21 however, so this PR adds this specification to the openpower config we're creating. Builds now succeeding[2].
