poke: Fix the reproducibility of installed scripts

Upstream does not support our default parallel "make -j install"[0]. So,
disable it with PARALLEL_MAKEINST = "-j1" to avoid non-reproducibility
where some scripts can be installed or not.

Explanation for the non-reproducibility:
There is a race condition between 2 actions at install around the
installed script in $pkgdatadir:
* Removal of existing scripts /usr/share/poke/*.pk
* Installation of default scripts in the same directory

Sadly, those 2 actions are not ordered. Depending on the build system
load, removal can (rarely) happen *after* the installation. In this
case, no script in present in /usr/share/poke/ when the install process
end.
