profiles: Compute manual database entries in parallel.

This provides a 36% speedup on an SSD and 4 cores for the 1.5K man pages
in the manual database derivation of:

  guix environment --ad-hoc jupyter python-ipython python-ipykernel

* guix/profiles.scm (manual-database)[build]: Add 'print-string',
'print', and 'compute-entry'.  Change 'compute-entries' to call
'compute-entry' in 'n-par-map'.
