ltp: Add recipe from OE

The pull request is to address [YOCTO #1568] - "Add recipe for ltp/posix tests and automate test". ltp is ported from OE and updated to latest version(20110915). Testcases are installed to ${D}/opt/ltp and POISX test suite is also copied into ${D}/opt/ltp/testcases folder. Include ltp to testapps list.

Note that some cases are removed from ltp since they depend on expect. Currently there is no expect recipe in OE and we will add it for enhancement next.

The following changes since commit e57935dc18d576feb1003b48e7cdc72a444131b8:
