[vcpkg-qmake] Remove unnecessary directory (#37752)

Recently when I was using vcpkg-qmake, I found that a function in the
`ports/vcpkg-qmake/vcpkg_qmake_configure.cmake` file was repeated:

be9eb66945/ports/vcpkg-qmake/vcpkg_qmake_configure.cmake (L143)
By running this line of code, we will configure the generated `qt.conf`
file. At the same time, if the
`${CURRENT_BUILDTREES_DIR}/${config_triplet}/` path does not exist, we
will also generate it.
Then we back up the environment variables and run the code
be9eb66945/ports/vcpkg-qmake/vcpkg_qmake_configure.cmake (L149)
to generate the existing path above.
