Add support for enabling dynamic dependency resolution

[siteshwar]

This issue tracks adding support for enabling --calculate-build-deps option in `csmock.

From manual page:

       --calculate-build-dependencies SRPM
              Evaluate and install all the SRPM (= file name, path on your sys‐
              tem) build dependencies, including dynamic dependencies in  %gen‐
              erate_buildrequires.  This is similar to the --installdeps option
              which only installs the static BuildRequires.

              Build  chroot-native  *.src.rpm  and *.nosrc.rpm files (the later
              only when %generate_buildrequires is  in  use!).   The  *.src.rpm
              records  the  corresponding  static list of build dependencies (=
              BuildRequires).  The *.nosrc.rpm records a full list of build de‐
              pendencies   (static   +   dynamic).    Test   with   rpm    -qpR
              [*.src.rpm|*.nosrc.rpm].

              Additionally,  provide  a  buildroot_lock.json file; this records
              the metadata  needed  for  a  hermetic  build  (see  also  --her‐
              metic-build).

@praiskup Today I realized what we were talking about a few months ago: --calcuclate-build-dependencies (unlike --installdeps) does not imply --no-clean. I think it is worth to mention this difference in the man page.
