Remove spurious warning messages about absolute filepaths.

During compilation of the Linux kernel messages like:

  absolute filepath blabla.h was IGNORED (correctness of build may be affected)

are issued.  They are wrong.  The problem is that -include or -imacro or even
source file names with absolute filepaths trigger a complaint from the caching
mechanism usually used for relative file names.

We correct this problem.

We also substitute fp_map for includepath_map, which is the now preferred term.
