[Buildroot] [git commit branch/next] package/pinentry: fix build with Qt4

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=1b59802dc0dcf1cb9332b2d7f9475343719b1d2c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Help configure find the correct moc, as the comment in m4/qt.m4 states:

    #configure tried to run $ac_cv_path_moc and the test didn't
    #succeed. If configure shouldn't have tried this one, set
    #the environment variable MOC to the right one before running
    #configure.

Fixes:
