textproc/ripgrep-all: depends on textproc/ripgrep

textproc/ripgrep-all will exit with a failure message when invoked if
ripgrep is not also installed. This commit changes the Makefile so that
textproc/ripgrep is listed as a runtime dependency, and therefore will
be automatically built and installed along with textproc/ripgrep-all.
