Fix a problem when add new ports on ports-mgmt category. ports-mgmt/Makefile

lines has 3 spaces before SUBDIR word and all other categories has 4.

I've asked pav@ if there is a default format of category Makefiles and he said
the number of spaces doesn't matter, so, i fix addport to respect the current
number of spaces and/or tabs the file has.
