Merge ~jnavila/curtin:lvm_int_bytes into curtin:master

[Jean-Noël AVILA]

When using automatic install script in subiquity with automated size
computation, the output is a double with no decimal, but lvcreate
fails with values of bytes presenting a decimal point.

[Michael Hudson-Doyle (mwhudson)]

I think it would be better to fix subiquity to never put floats into the config file TBH.

Force human2bytes to always return an int

All sizes in bytes can only be integer. Moreover, for all users of
this function, the output can be printed without a decimal point
appearing.
