meson: Enable vimc IPA for tests

Vimc pipeline handler is enabled unconditionally if the meson config
option '-Dtest' is true. However, this is not true for the vimc IPA.
Hence, a meson configuration such as:

    -Dpipelines=raspberrypi -Dipas=raspberrypi -Dtest=true

will include the vimc pipeline handler (in addition to raspberrypi)
but will skip the vimc IPA which can lead to failure of unit tests
that depends on vimc to execute.

One such unit test was identified as a result of this issue on
RaspberryPi:

ERROR IPAModule ipa_module.cpp:278 ipa_vimc.so: Failed to open IPA library: No such file or directory
test IPA module src/ipa/vimc/ipa_vimc.so is invalid

due to the non-existent ipa_vimc.so.

Fix this by including the vimc IPA unconditionally when the tests are
enabled, similar to how the vim pipeline-handler is included.
