freerdp3: install cmdline-tests data for ptest

TestCommandLineToCommaSeparatedValues fails because its JSON test cases
are never installed.

With no arguments the test runs runJsonTests(), which globs
TEST_SOURCE_DIR/cmdline-tests/*.json via FindFirstFileA and returns -1
when the directory cannot be opened. do_configure:prepend already
rewrites TEST_SOURCE_DIR for this CMakeLists to ${PTEST_PATH}/test, and
the built driver confirms it:

  $ strings Testing/TestWinPRUtils | grep -e cmdline-tests -e ptest/test
  cmdline-tests
  cmdline-tests%c*.json
  /usr/lib/freerdp3/ptest/test

but do_install_ptest only copies *bmp out of
winpr/libwinpr/utils/test, so /usr/lib/freerdp3/ptest/test/cmdline-tests
does not exist on target and the glob always fails. Copy the directory
alongside the other test data.
