package/python3: fix install when tk is disabled

Fixes the following failure in the install step of host-python3:
    ...
    /usr/bin/install -c -m 644 pyconfig.h output/host/include/python3.12/pyconfig.h
    [ERROR] _tkinter failed to import: output/build/host-python3-3.12.1/build/lib.linux-x86_64-3.12/_tkinter.cpython-312-x86_64-linux-gnu.so: undefined symbol: Tcl_AddErrorInfo
    The following modules are *disabled* in configure script:
    _ctypes_test          _testbuffer           _testcapi
    _testclinic           _testimportmultiple   _testinternalcapi
    _testmultiphase       _xxtestfuzz           xxsubtype

    Following modules built successfully but were removed because they could not be imported:
    _tkinter

    Checked 110 modules (31 built-in, 54 shared, 15 n/a on linux-x86_64, 9 disabled, 0 missing, 1 failed on import)
    ...
    /usr/bin/install -c -m 644 ./Lib/types.py output/host/lib/python3.12
    /usr/bin/install: cannot stat 'Modules/_tkinter.cpython-312-x86_64-linux-gnu.so': No such file or directory
    /usr/bin/install -c -m 644 ./Lib/typing.py output/host/lib/python3.12
    make[3]: *** [Makefile:2068: sharedinstall] Error 1
    ...
