[PATCH] linux-user/syscall.c: malloc to g_try_malloc

[Ahmed Abouzied <email@aabouzied.com>]

Use g_try_malloc instead of malloc to alocate the target ifconfig.
Also replace the corresponding free with g_free.

Hello, 

I noticed that there was a `malloc` call in this file. It seems that it
was added by the commit 22e4a267 (3 years ago) which was after the commit
0e173b24 (6 years ago) that replaced malloc calls with glib alternative calls.

There is no issue for this on Gitlab. Should I have created an issue
first? 

Best regards,
