brewer.awk: Close file after opening.

macOS awk seems to have a limit to how many files it will open at once.

Fixes this error on macOS awk:
$ make
...
awk -f brewer.awk ../../lib/common/brewer_colors
awk: colortmp/brbg7 makes too many open files
 input record number 131, file ../../lib/common/brewer_colors
 source line number 13
make: *** [colors.html] Error 2
