cmake: Organize aom.pc and install target support.

- Move the CMake scripting supporting the install target
  and aom.pc generation into build/cmake/aom_install.cmake.
- Fix the format of aom.pc per comments in linked bug.
- Fix the libdir value: build it using exec_prefix.
- Fix the Libs value: remove private libs.
- Fix dependency issue: aom.pc was not built post clean.

Also fixes an error at configuration time,
f7e0b7f305b1dfdd352bf2c17561b916fcec6212 missed one usage of
pkg_config.cmake, and it was complaining about the missing
GNUInstallDirs related arguments.
