Absolute value: sometimes CAS is very clever, sometimes not!

For the Prime, I can add code for simple situations like this one. But I can not enable the full Xcas code for several reasons (if the Prime was running linux, it would be different).

I admit I compared to desktop version and it's most unfair
since the full version is not available - not even on HW 2 with more RAM.

Another quick fix for the simple cases of ABS.
Note: the TI Nspire CAS could do it - as pointed out by a member in a post.
Yet again the HP Prime excels with it's limited version of xCAS

Thank you, Monsieur Parisse!
