Call realpath() to strip out any levels of indirection required in
referencing the root build directory.
This simplifies the debug output when reporting and parsing paths.

Similarly to libcameraBuildPath(), there's a need to locate resources
within the source tree when running libcamera without installing it.
Support this use case with a new utils::libcameraSourcePath() function.
The implementation uses a symlink from the build root to the source root
in order to avoid hardcoding the path to the source root in the
libcamera.so binary.

Add a utils::join() function to join elements of a container into a
string, with a separator and an optional conversion function if the

The two callers of functions libcameraPath() and isLibcameraInstalled()
end up using the same process and finally use the path with
libcamera.so. Hence write a function libcameraBuildPath() which
combines their functions and returns the root of the build sources
when the library has not been installed, but is running from the build
tree, thereby making call sites simpler.
When the library is installed, libcameraBuildPath() will return an empty
string.
Make changes in the call sites accordingly.

The IPA proxy manager will need to find the libcamera build path exactly
the same way as the IPA module mnager. Move the isLibcameraInstalled()
and libcameraPath() functions to utils to make them reusable.

strlcpy is available in libbsd, bionic, musl, and ulibc, but not in glibc.
Instead of checking for strlcpy availability and modifying dependencies,
implement it in utils, as a wrapper around strncpy.
