dev-manual: use "strace" for PV example, not cdrtools

Section 3.3.5, "Fetching Code", uses the cdrtools recipe as an example
for showing the use of PV, but that's a bad example since the current
cdrtools recipe file contains:

  SRC_URI = " \
  ${SOURCEFORGE_MIRROR}/project/cdrtools/cdrtools-${REALPV}.tar.bz2 \
  ...

  PV = "3.01a31+really3.01"
  REALPV = "3.01"

which is not exactly the point the dev manual is trying to make, so
replace with simpler strace recipe.
