allow optional whitespace in dirty scheduler erl options
The +SDcpu, +SDPcpu, and +SDio options did not properly handle having their
arguments immediately following them without intervening whitespace,
e.g. +SDio20 was treated as an error. Fix all the dirty scheduler command
line options so they handle optional whitespace between them and their
associated arguments.
