[begemot] monlib: fix alignment for 32-bit arch /

`pair<..., ui64>` is aligned by 8 bytes, whereas
`TExplicitHistogramSnapshot` contains only ui32 which does not have to be 8-byte-aligned.

This patch fixes a static assert from the line 203: `alignof(TExplicitHistogramSnapshot) == alignof(TBucket)`
