gdbstub: Replace strcpy() by strscpy()
The strcpy() function is being deprecated. Replace it by the safer
strscpy() and fix the following Coverity warning:
"You might overrun the 1024-character fixed-size string remcom_in_buffer
by copying cmd without checking the length."
Addresses-Coverity-ID: 138999 ("Copy into fixed size buffer")
