Add module name to preprocessor defines

[thegecko]

@bogdanm, this addition was suggested by @jacobrosenthal in #774 to fix #773.

Do you see any problem (specifically with symbol name clashes) with this change?

It's already defined as YOTTA_MODULE_NAME: http://docs.yottabuild.org/reference/buildsystem.html /

yotta/yotta/lib/templates/base_CMakeLists.txt

Lines 119 to 121 in 7cec9c6

	# make YOTTA_MODULE_NAME available as a preprocessor symbol when
	# compiling this module:
	target_compile_definitions({{ component.getName() }} PRIVATE "-DYOTTA_MODULE_NAME={{ component.getName() }}")

Thanks @autopulated! I'll close this, then. @jacobrosenthal please reopen if there is any issue.
