Fix string overflow warning
With GCC 9.2 the following warning is emitted when building hstr:
In file included from /usr/include/string.h:494,
from include/hstr_utils.h:26,
from hstr_utils.c:19:
In function ‘strncpy’,
inlined from ‘get_shell_name_by_ppid’ at hstr_utils.c:220:15:
/usr/include/bits/string_fortified.h:106:10: warning:
‘__builtin___strncpy_chk’ output truncated before terminating nul
copying as many bytes from a string as its length [-Wstringop-truncation]
106 | return __builtin___strncpy_chk (__dest, __src, __len, __bos (__dest));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
hstr_utils.c: In function ‘get_shell_name_by_ppid’:
hstr_utils.c:220:47: note: length computed here
220 | strncpy(name,shell,sizeof(char)*strlen(shell));
| ^~~~~~~~~~~~~
By using the destination buffer size as the number of characters to copy this warning is avoided.
