[PATCH] cpukit/libmisc/dumpbuf/dumpbuf.c: Fix compilation warnings

[Martin Galvan]

Compiling dumpbuf.c causes the following warning to be issued:

warning: pointer targets in passing argument 1 of 'snprintf' differ in signedness [-Wpointer-sign]

This happens because line_buffer is declared as unsigned.

Closes #2411.
