pnmtohex: Optionally use pkg-config for netpbm
As of libnetpbm11 in Debian/Ubuntu, the netpbm header files are no
longer located in the root include directory, but in a netbpm
subdirectory. Fortunately the same version added support for
pkg-config.
Support both old and new systems by using pkg-config, when available.
