ARM: 8397/1: fix vdsomunge not to depend on glibc specific error.h
ARM: 8397/1: fix vdsomunge not to depend on glibc specific error.h

If the host toolchain is not glibc based then the arm kernel build
fails with

 arch/arm/vdso/vdsomunge.c:53:19: fatal error: error.h: No such file or directory

error.h is a glibc only header (ie not available in musl, newlib and
bsd libcs).  Changed the error reporting to standard conforming code
to avoid depending on specific C implementations.
