[PATCH] Fix test failures when TUI is not enabled

[Bernd Edlinger <bernd.edlinger@hotmail.de>]

This adds some missing require allow_tui_tests.

When tui is not enabled those test cases do typically
fail, but most of them only after a long time-out:

FAIL: gdb.base/new-ui.exp: do_test_invalid_args: new-ui with tui
FAIL: gdb.base/wrap-line.exp: term=ansi: width-hard-coded: wrap (timeout)
FAIL: gdb.base/wrap-line.exp: term=ansi: width-auto-detected: wrap (timeout)
FAIL: gdb.base/wrap-line.exp: term=xterm: width-hard-coded: $gdb_width == $readline_width
FAIL: gdb.base/wrap-line.exp: term=xterm: width-hard-coded: wrap (timeout)
FAIL: gdb.base/wrap-line.exp: term=xterm: width-auto-detected: $gdb_width == $readline_width
FAIL: gdb.base/wrap-line.exp: term=xterm: width-auto-detected: wrap (timeout)
FAIL: gdb.tui/wrap-line.exp: width-hard-coded: cli: wrap
FAIL: gdb.tui/wrap-line.exp: width-hard-coded: cli: prompt after wrap
FAIL: gdb.tui/wrap-line.exp: width-auto-detected: cli: wrap
FAIL: gdb.tui/wrap-line.exp: width-auto-detected: cli: prompt after wrap
