Fix keymap test during make distcheck

The keys/keymap test preformed by src/keymap/check-keymaps.sh must
find both keys.txt and the keymap directory.  When building out of
the source tree, eg when doing `make distcheck`, these are located
at ${top_builddir}/src/keymap/keys.txt and ${top_srcdir}/keymap/,
respectively.  This patch fixes the build so that these are now
correctly found.
