Clean up #include directives This is subtle, but #include <header.h> searches directories specified with -I, then system include directories. #include "header.h" searches the current source directory, then directories specified with -I, then system include directories. Using bracketed #include directives for jpeglib.h, jinclude.h, jerror.h, cdjpeg.h, and turbojpeg.h only worked because the build system explicitly passed -I{source_directory}/src/ to the compiler. Referring to 51cee0362998ec6f1eabac1e795f3b6e3ee639ea, it's better for the source code to have as few dependencies on our specific build system as possible. Since jpeglib.h, jinclude.h, jerror.h, and turbojpeg.h can be installed in system include directories, it's also better for internal references to those headers to resolve internally first, to avoid potential conflicts between the system-installed version of libjpeg-turbo and the version being built. (Such conflicts would never have occurred with our build system, but they might have occurred due to misintegration with a downstream build system.)
