[OE-core] [PATCH 04/16] fix_buildpaths.bbclass: add bbclass to fix build path

[Hongxu Jia]

Define variable PACKAGE_BUILDPATH_TEXT_FILES to list files that have
build paths and remove these paths at do_package time. It supports
package override while files exist in conditionally generated package.
(such as ${PN}-ptest is conditionally generated)

Define variable PACKAGE_BUILDPATH_TEXT_PATTERNS to list build path
patterns, which used by sed, it removes --sysroot and
-fdebug-prefix-map in text files by default.

Define python function to remove build path in variable.

Define python function to remove build path in python compiled
code.
