cmake: install individual libraries (common, phy, etc)

this seems to be important for package maintainers
or people who use srslte components in other projects
thar require to link against static libs

so besides installing headers, the apps and the RF lib, we also
install all individual libraries

this fixes https://github.com/srsLTE/srsLTE/issues/500#
and https://github.com/softwareradiosystems/srsLTE/issues/1754
