[PATCH] usr/include: refactor .gitignore

[Masahiro Yamada]

The current .gitignore intends to ignore everything under usr/include/
except .gitignore and Makefile.

A cleaner solution is to use the '/' suffix, which make the pattern match
to only directories. It works well here because exported headers are all
located in sub-directories such as <linux/*.h>, <asm/*.h>, etc.
