package/util-linux: add dependency to BR2_USE_MMU when needed

Upstream added fork() to lib/canonicalize.c in version 2.34[1]
e101a9eb0f

but the resulting build errors on non-mmu archs were most likely masked
by previous build errors which are already fixed.

lib/canonicalize.c as part of libcommon is widely used so we need to add
the dependency to many Config.in options.

For an overview about its usage see
output/build/util-linux-2.41.2$ grep -r "LDADD = \$(LDADD) libcommon.la" * | grep Makemodule | cut -d ":" -f 2 | sort

Fixes:

[1] Added to buildroot with commit bb216ed060
    in 2019.
