[testsuite] Remove obsolete ada/acats/overflow.lst file

[Eric Botcazou]

It is used to specify which files are compiled with -gnato, but the switch has 
been the default for at least a decade.

Tested on x86-64/Linux, applied on the mainline.

        * ada/acats/overflow.lst: Delete.
        * ada/acats/run_all.sh: Do not process overflow.lst.
