minstall: Add --skip-subprojects option

By default all subprojects are installed. If --skip-subprojects is given
with no value only the main project is installed. If --skip-subprojects
is given with a value, it should be a coma separated list of subprojects
to skip and all others will be installed.

Fixes: #2550.
