[PATCH] mesh: Move local basename into utility file

[Khem Raj <raj.khem@xxxxxxxxx>]

Defining an override via a missing.h can prove difficult when a file
needs to use basename and dirname both the APIs and needs to include
libgen.h for them, in such situations there will be signature clash
for basename function.
