use clean_dir instead of remove_dir on installation directory in custom easyblock for Molpro

[smoors]

(created using eb --new-pr)

requires:

• add clean_dir function, use it to try to empty install dir if removing it fails easybuild-framework#4932

[boegel]

Unsure here, because I can't test it myself, don't have access to Molpro.

Maybe @bedroge can take a look (cfr. easybuilders/easybuild-easyconfigs#20491) ?
