[PATCH] debian.bbclass: Fix hardcoded "lib" reference

[Richard Purdie <richard.purdie@linuxfoundation.org>]

This patch removes a hardcoded "lib" reference from debian.bbclass
allowing libdirs like "lib64" to be used. Whilst working on this area of
code, a similar assumption about "bin" is removed and the regular
expression compilation is moved to the parent function since it doesn't
change and this will improve the speed of the code.
