Takuya ASADA 6ac254fbcb dist: change nomerges=1 on block devices during fstrim execution ...

We have problem to run fstrim with nomerges=2, so we need to change
the parameter to 1 during fstrim execution.
To do this, this fix changes follow things:
 - revert dropping scylla_fstrim on Ubuntu 16.04/CentOS
 - disable distribution provided fstrim script
 - enable scylla_fstrim on all distributions
 - introduce --set-nomerges on scylla-blocktune
 - scylla_fstrim call scylla-blocktune by following order:
   - 'scylla-blocktune --set-nomerges 1'
   - 'fstrim' for each devices
   - 'scylla-blocktune --set-nomerges 2'

Fixes #2649
