build: fix install from any directory with Meson 0.55

Install command on Windows for Meson >= 0.55.0 referenced the script
by a plain string, assuming the build directory to be directly under
the source tree root.
This resulted in an error when the assumption did not hold:

    c:\python\python.exe: can't open file
    '../buildtools/symlink-drivers-solibs.py':
    [Errno 2] No such file or directory

Use files() to make a valid script path for any build directory.
