QWidget: simplify reading of an env-var in create()

Instead of initializing paintOnScreenEnv to -1 (thus forcing the
variable into the data segment), and then overwriting the -1 with
a read from the env-var, dynamically initialize the variable from
the env-var directly, thus allowing the variable back into the bss
segment (which doesn't occupy storage in the executable).

There may have been a reason to do it this way when the old code
could fail due to the memory allocation involved, but now with
qEnvironmentVariableIntValue(), that is no longer a reason.
