[Replicant] [libsamsung-ipc] [PATCH 3/6] tests: ipc-modem: fix test with out of tree builds

[Denis 'GNUtoo' Carikli]

When running the tests in an out of tree build directory (here in
scripts/src/), without that fix, we have the following error in
src/samsung-ipc/tests/test-suite.log when running 'make check':
    FAIL: ipc-modem
    ===============

    Traceback (most recent call last):
      File "[...]/scripts/src/tools/../../../tools/ipc-modem.py", line 79, in <module>
        rc = main()
      File "[...]/scripts/src/tools/../../../tools/ipc-modem.py", line 74, in main
        ipc_modem = IpcModem()
      File "[...]/scripts/src/tools/../../../tools/ipc-modem.py", line 39, in __init__
        ipc_modem = sh.Command(srcdir + os.sep + 'ipc-modem')
      File "/usr/lib/python3.9/site-packages/sh.py", line 1342, in __init__
        raise CommandNotFound(path)
    sh.CommandNotFound: ../../../tools/ipc-modem
    FAIL ipc-modem.py (exit status: 1)
