LoongArch: Select HAVE_ARCH_SECCOMP to use the common SECCOMP menu

[ Upstream commit 6b79ecd084c99b31c8b4d0beda08893716d5558e ]

LoongArch missed the refactoring made by commit 282a181b1a0d ("seccomp:
Move config option SECCOMP to arch/Kconfig") because LoongArch was not
mainlined at that time.

The 'depends on PROC_FS' statement is stale as described in that commit.
Select HAVE_ARCH_SECCOMP, and remove the duplicated config entry.

-         This kernel feature is useful for number crunching applications

-         the process as file descriptors supporting the read/write
-         syscalls, it's possible to isolate those applications in
-         their own address space using seccomp. Once seccomp is
-         enabled via /proc/<pid>/seccomp, it cannot be disabled
-         and the task is only allowed to execute a few safe syscalls
-         defined by each seccomp mode.
