tools/nxstyle.c: Correct false alarm detection (#106)

Browse Source 
Commit cf5d17f795 added logic to detect #define pre-processor definitions outside of the "Pre-processor Definitions" file section.  That commit was verified against numerous .c source files.  But not against any .h header files.

When run against a header file, that change causes a false alarm warning like:

  file:line:pos: warning: #define outside of 'Pre-processor Definitions' section

That is caused the idempotence, guard definition that must appear in the header file BEFORE the first file section.

This commit adds logic to nxstyle to ignore pre-processor definitions in header files that occur before the first file section is encountered.
