Improve errExit error messages

Changes: * Move msg to the end of errExit (right before perror(3p)) * Include the full file path (within the repository) * Add "()" to function name for clarity Before: Error malloc: main.c:123 main: Cannot allocate memory After: Error src/firejail/main.c:123 main(): malloc: Cannot allocate memory Note: This clarifies which is the exact file that the error message comes from, as there are many source files with the same name. For example: $ git ls-files 'src/*/main.c' | wc -l 20
