lib: Fix out-of-bounds write when concatenating commands
This commit fixes the hci_commandstostr() command by writing new line
character in place of trailing space when wrapping long lines. Previous
approach was to append new line character to existing string, which
caused buffer overflow when there was more than 9 lines in the output
string.
Also, the last trailing space is removed in order to return
trailing-spaces-free string to the caller.
