Update makedepf90 to 2.8.8.
Patch provided by MAINTAINER, Emil Skoeldberg via PR 34306.

Changes since 2.8.4:

* 2.8.8 (13.6 2006)
    - Close include files when we are done reading them.

* 2.8.7 (13.6 2006)
    - More informative error messages in case of I/O errors.

* 2.8.6 (31.3 2006)
    - Fixed problem with continuation lines in fixed form, introduced in
      version 2.8.5.

* 2.8.5 (29.3 2006)
    Fixed two bugs
     - Some cpp-lines continued by a \ at the end made makdepf90 hang.
     - In fixed form, makedepf90 was sometimes tricked into beliving it was
       inside a string, when it actually wasn't.
