build: fix warnings when running external commands

Meson 0.61.1 is giving warnings that the calls to run_command do not
always explicitly specify if the result is to be checked or not, i.e.
there is a missing "check" parameter. This is because the default
behaviour without the parameter is due to change in the future.

We can fix these warnings by explicitly adding into each call whether
the result should be checked by meson or not. This patch therefore
adds in "check: false" to each run_command call where the result is
being checked by the DPDK meson.build code afterwards, and adds in
"check: true" to any calls where the result is currently unchecked.
