vboxguestdrivers: depend on virtual/libc for userspace mount utility

Browse Source 
do_compile failed building the userspace mount helper:

  mount.vboxsf.c:38:10: fatal error: errno.h: No such file or directory
  vbsfmount.c:36:10: fatal error: assert.h: No such file or directory

The kernel modules build fine; only the userspace utility fails. This
recipe inherits module, and module.bbclass sets INHIBIT_DEFAULT_DEPS=1
(kernel modules build -nostdinc and do not need libc). That suppresses
BASE_DEFAULT_DEPS (virtual/cross-cc virtual/compilerlibs virtual/libc)
and only re-adds virtual/cross-cc + virtual/cross-binutils, so the
target libc headers and crt objects are never staged into
recipe-sysroot. But this recipe also compiles an ordinary hosted
userspace program (utils/mount.vboxsf), which needs libc.

Add back virtual/compilerlibs and virtual/libc. Using the same
virtual/* provider names OE lists in BASE_DEFAULT_DEPS keeps this
correct across libc (glibc/musl) and toolchain (gcc/clang) choices.
Verified errno.h is staged and mount.vboxsf compiles, links and is
packaged into ${base_sbindir}.
