MC: Rename isVirtualSection to isBssSection

The term BSS (Block Started by Symbol) is a standard, widely recognized
term, available in the a.out object file format and adopted by formats
like COFF, XCOFF, Mach-O (called S_ZEROFILL while `__bss` is also used),
and ELF. To avoid introducing unfamiliar terms, we should use
isBSSSection instead of isVirtualSection.
