app/vmalert/rule: reduce number of allocations for getStaleSeries fn (#6269)
Allocations are reduced by re-using the byte buffer when converting
labels to string keys.
```
name               old allocs/op  new allocs/op  delta
GetStaleSeries-10       703 ± 0%       203 ± 0%   ~     (p=1.000 n=1+1)
```
