Subject: [PATCH v2] fix compile procan.c failed

1. Compile socat failed if out of tree build (build dir != source dir)
...
gcc -c -D CC="gcc" -o procan.o procan.c
cc1: fatal error: procan.c: No such file or directory
...
Explicitly add $srcdir to makefile rule

2. Compile socat failed if multiple words in $(CC), such as CC="gcc -m64"
...
from ../socat-1.8.0.0/procan.c:10:
../socat-1.8.0.0/sysincludes.h:18:10: fatal error: inttypes.h: No such file or directory
   18 | #include <inttypes.h>   /* uint16_t */
...

In commit [Procan: print umask, CC, and couple more new infos][1],
it defeines marcro CC in C source, the space in CC will break
C source compile. Use first word of $(CC) to defeine marco CC
