config: detect uuid_generate_sha1() function definition

Browse Source 
Some systems (like FreeBSD and Centos 7) do not have this
method in their system libraries.
To let bdev UUIDs be generated with SHA1, detect if this
symbol is present. Otherwise, define a new symbol that
indicates a need to use internal implementation of
uuid_generate_sha1() method.
