build: avoid overlinking

A while ago telemetry was added in 57ae0ec6 and it also added as-needed
to config/meson.build. This seems no more needed these days as due to other
build changes the ordering in buildlogs is:
  [...] -lrte_telemetry [...] -Wl,--no-as-needed [...]
Which means telemetry no more benefits from --no-as-needed anyway.

Overlinking problems get triggered by the meson generated pkgconfig which
will have:
   [...] -Wl,--no-as-needed <somelibsusedbydpdk>
This will overlink <somelibs> and in addition anything that follows
as it also doesn't wrap back to --as-needed. So if a projects includes
dpdk libs + <other> it will also consider <other> with --no-as-needed.
