[PATCH] Use foreach, not lmap, for tcl <= 8.5 compat

[Jørgen Kvalsvik]

lmap was introduced in tcl 8.6, and while it was released in 2012, lmap
does not really make too much of a difference to warrant the friction on
consverative (and relevant) systems.

gcc/testsuite/ChangeLog:

        * lib/gcov.exp: Use foreach for tcl <= 8.5.
