gmacros: Fix G_[UN]LIKELY to not mask -Wparentheses

Browse Source 
A double paren forces the compiler to assume that the
statement is right.  That may not be the case.

This is essentially reverting b44fba25fb.
See https://bugzilla.gnome.org/show_bug.cgi?id=760215.

It's more morth to allow find common mistakes (= instead of ==
in conditionals) than masking them to make some rarely used
code work.
