tests: Merge iochannel-test into io-channel tests in glib directory

Browse Source 
We’re trying to eliminate the legacy `tests/` directory. This commit
moves the code from `tests/iochannel-test.c` into
`glib/tests/io-channel.c` and ports it to the latest GLib test coding
standards:
 * Change `g_assert()` to `g_assert_*()`
 * Print verbose messages with `g_test_message()`
 * Rename some variables to conform to modern conventions
 * Use `GTest`
