meson: simplify use of the common-main library

The "common-main.c" file is used by multiple executables. In order to make it easy to set it up we have created a separate library that these executables can link against. All of these executables also want to link against `libgit.a` though, which makes it necessary to specify both of these as dependencies for every executable. Simplify this a bit by declaring the library as a source dependency: instead of creating a static library, we now instead compile the common set of files into each executable separately.
