tools/cgget: replace strcat() with strncat()

Fix copy into fixed size buffer warning, reported by Coverity tool:

CID 258284 (#4 of 4): Copy into fixed size buffer (STRING_OVERFLOW)1.
fixed_size_dest: You might overrun the 4096-character fixed-size string
tmp_val by copying tok without checking the length.

In indent_multiline_value(), warned about the usage of strcat(), that
might overwrite the string. Fix it by replacing strcat() -> strncat()
in the function.
