hplip: 3.18.3 -> 3.18.5

Also fixes multiples issues:

 -  broken plugins:

     -  `fax_marvell.so file is not present or symbolic link is missing`
     -  `lj.so library file doesn't have user/group execute permission.`
     -  `bb_escl.so file is not present or symbolic link is missing`

 -  multiple error during configuration phase which prevented `*.ppd`
    generation:

     -  `ppdc: Unable to find include file "<font.defs>"`
     -  patched configure time `perl` script
     -  patched use of `file`

 -  some potentially problematic filter and services:

     -  patched reference to ghost script and fonts dir in filter.
     -  patched usb configuration service.

 -  patch scripts so that they refer to valid location.

Add some options:

 -  `withStaticPPDInstall`: Install `*.ppd` files along with `*.drv`.
    When true, configure outputs: `checking for cups ppd install... yes`.
