Reenabled check-import.sh which tests imports to Ansible Galaxy

Reverted commit 1f3417cdef [1] which disabled check-import.sh script.
Python module galaxy_importer will return a non-zero return value on
errors since commit 4f5fd0f29c [2].

Use galaxy-importer 0.3.1 for Ansible 2.9 and galaxy-importer 0.3.2
for later Ansible releases because galaxy-importer moved from ansible
2.9 to ansible-core 2.11 in 0.3.2 [3].
