selftests/namespaces: add uid_map/gid_map range tests
Check that a uid_map or gid_map line with a value that does not fit in
u32, or with a negative value, is rejected with EINVAL and installs
nothing, for each of the three fields.
Check that in-range lines are still accepted and read back unchanged:
a plain single-id mapping, first id 0, the largest valid first id
4294967294, and a line with extra spaces between the fields. When run
as root in the initial user namespace, also check that the largest
count, "0 0 4294967295", is accepted when written by the parent into
the uid_map of a child namespace; an unprivileged writer can only map
a single id.
