package/libgpg-error: needs MMU

Browse Source 
libgpg-error imported code using fork() in commit [1] and enabled it
soon after in [2]. Those commits were first included in libgpg-error
version 1.28.

For reference, the libgpg-error Buildroot package was updated to that
version in commit [3].

When Buildroot configuration has no MMU support (e.g. BR2_USE_MMU is
not set), libgpg-error fails to build with error:

    /build/host/opt/ext-toolchain/arm-buildroot-uclinux-uclibcgnueabi/bin/ld.real: ./.libs/libgpg-error.a(libgpg_error_la-spawn-posix.o): in function '_gpgrt_process_spawn':
    spawn-posix.c:(.text+0x630): undefined reference to 'fork'

This issue can be observed with the command:

    utils/test-pkg -a -p libgpg-error

It will show few build failures:

    ...
       bootlin-armv7m-uclibc [ 6/41]: FAILED
    ...
    bootlin-m68k-5208-uclibc [ 8/41]: FAILED
    ...

This commit fixes the issue by adding the dependency on BR2_USE_MMU
in BR2_PACKAGE_LIBGPG_ERROR_ARCH_SUPPORTS. Doing so will
automatically propagates this dependency to all packages using
libgpg-error (and thus, already depending on this _ARCH_SUPPORTS).
