Fixes #35785

Internal binaries are installed to CMAKE_INSTALL_LIBEXECDIR. That defaults to libexec, but a distro can set it to something else (Arch uses lib). The bitcoin wrapper always looked in ../libexec under the install prefix, so those builds fail after cmake --install for bitcoin-node, chainstate, and the other internal binaries.

The wrapper now uses the same CMake value.

tool_bitcoin.py copies the wrapper into a fake prefix/bin and bitcoind only into prefix/<LIBEXECDIR>, then runs it by absolute path.

Putting the binary in a different directory should fail. Normal functional tests miss this because every binary sits next to the wrapper in the build tree.

build: honor CMAKE_INSTALL_LIBEXECDIR in wrapper

The wrapper always looked in ../libexec for binaries, but
install_binary_component(INTERNAL) uses CMAKE_INSTALL_LIBEXECDIR.
Distro builds that set that to lib then fail after install.
Fixes #35785
