Please install mercurial on buildbot XY

[Michael Heimpold]

Hi,

it seems that at least one buildbot is missing mercurial, see
https://downloads.lede-project.org/snapshots/faillogs/arm_arm926ej-s/packages/
libcanfestival/compile.txt

<snip>

I'm not sure how to find out _which_ buildbot produced this
compile log, this is why I post it here and hope, that all
buildbot admins could check their machine(s) :-)

Thnx,
