[OE-core] [PATCH v2] kernel.bbclass: fix emit_depmod_pkgdata() workdir

[Ioan-Adrian Ratiu]

bitbake commit 67a7b8b02 "build: don't use $B as the default cwd for
functions" breaks the assumption that this function is running under
${B}. This causes build failures because System.map is under ${B}.
Fix this by using an absolute path instead of relying on cwd.
