[Buildroot] [PATCH v4 6/7] pkg-cmake.mk: add PATH in the configure command environment

[Samuel Martin <s.martin49@gmail.com>]

Because BR2_PATH is not exported in the environment beforehand running
cmake, it is necessary to add it on the cmake configure command.

changes v3 -> v4:
- rebase
- rename BR2_PATH -> BR_PATH

changes v2 -> v3:
- rebase
- no one-line commit log (ThomasP)

changes v1 -> v2:
- remove explicit PATH=... in configure commands in pkg-autotools.mk
  because it is already added via *_CONFIGURE_OPTS (ThomasP), and
  reword the commit message.
