[PATCH 7/8] testsuite: use grep -E instead of egrep

[Xi Ruoyao via Gcc-patches]

egrep has been deprecated in favor of grep -E for a long time, and the
next grep release (3.8 or 4.0) will print a warning of egrep is used.
Stop using egrep so we won't see the warning.

gcc/testsuite/ChangeLog:

        * ada/acats/run_all.sh: Use grep -E instead of egrep.
        * go.test/go-test.exp: Likewise.
