Corrected the top-level Makefile to add "/share" after the prefix, so
that the open_pdks scripts go in ${prefix}/share/pdk/bin/ as they are
expected to, while the SkyWater PDK goes in ${prefix}/share/pdk/sky130A/.
Changed the instructions in docs.txt so that the distributed install
works as advertized (swapped the definitions suggested for prefix and
DESTDIR).

     Packagers and administrators that want to create a directory which
