meson.bblcass: Remove empty egg-info directories before running meson

Browse Source 
sstate.bbclass no longer removes empty directories to avoid a race (see
commit 4f94d929 "sstate/staging: Handle directory creation race issue").
Unfortunately Python apparently treats an empty egg-info directory as if
the version it previously contained still exists and fails if a newer
version is required, which Meson does. To avoid this, make sure there
are no empty egg-info directories from previous versions left behind.
