tools: bpftool: fix potential format truncation
GCC 7 complains:
xlated_dumper.c: In function ‘print_call’:
xlated_dumper.c:179:10: warning: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size between 249 and 253 [-Wformat-truncation=]
"%+d#%s", insn->off, sym->name);
Add a bit more space to the buffer so it can handle the entire
string and integer without truncation.
