Fix gdb procfs.c compilation on Solaris

Prompted by the creation of the gdb 8.0 branch, I tried to build it on
x86_64-pc-solaris2.12, but failed:

/vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/procfs.c: In function `target_ops* procfs_target()':

   t->to_create_inferior = procfs_create_inferior;

This can easily be fixed by the following patch.

	* procfs.c (procfs_create_inferior): Change prototype to match
