[PATCH 1/2] lttng-tools ptest: add missing dependencies

[Jonathan Rajotte <jonathan.rajotte-julien@efficios.com>]

Multiple tests are failing due to missing dependencies on a bare
core-image-minimal build with only lttng-tools ptest present.

"getconf LONG_BIT" is used to get the bitness of the host to run the
correct consumerd. Depend on glibc-utils.

perl-module-overloading is needed to validate trace. babelstats.pl

"head -c" is used to generate a random string. It is easier to depends
on coreutils to get a feature complete "head" than to enable to "fancy
head" feature of busybox. See utils.sh randstring.

"taskset" is used in a couple of scripts to ensure that events generated
finish in the same buffer. Depend on util-linux.

I also submitted the following patches [1] [2] to lttng upstream. It
should help get the ptest sucess ratio up when they are merged. They
should be released in the upcoming month.
