testsuite: Fix false FAILs on too long base directory

I was getting

and also:

(gdb) FAIL: gdb.guile/scm-value.exp: argv[0] should be available on this

gdb/testsuite/ChangeLog
2016-01-11  Jan Kratochvil  <jan.kratochvil@redhat.com>

	* gdb.guile/scm-value.exp (test_value_in_inferior): Set print elements
	and repeats to unlimited.
	* gdb.python/py-value.exp: Likewise.
	* lib/gdb.exp (gdb_has_argv0): Save and temporarily set print elements
	and repeats to unlimited.
