s390/linkage: increase asm symbols alignment to 16
Both clang and gcc (for -march=z13 and later) align functions to 16
bytes at -O2 to benefit branch prediction.
Make asm symbols alignment consistent with that.
This also benefits potential ftrace code patching, which is currently
able to patch 8 aligned bytes at once.
With defconfig this currently increases .text size by 4104 bytes.
