bitbake: bitbake-user-manual-metadata.xml: Added section on pathname syntax

Added a brief subsection to the "Basic Syntax" section that
describes the issue using the tilde character (~) when providing
a pathname as part of a statement.  BitBake does not expand
this character like the shell does.  We recommend to not use
it in pathnames.

+                When specifying pathnames for use with BitBake,
+                do not use the tilde ("~") character as a shortcut
+                for your home directory.
+                Doing so might cause BitBake to not recognize the
+                path since BitBake does not expand this character in
+                the same way a shell would.
