sepolgen: Support latest refpolicy interfaces

Some refpolicy interfaces use:

* "$" character in paths, for example in kernel/selinux.if:

    genfscon selinuxfs /booleans/$2 gen_context(system_u:object_r:$1,s0)

* empty members in ifelse statement, for example in system/init.if:

    ifelse(`$5',`',`',`
        ...
    ')

Modify sepolgen/refparser grammar accordingly.

This fixes the following syntax errors reported by sepolgen-ifgen:

    /usr/share/selinux/refpolicy/include/kernel/selinux.if: Syntax error
    on line 43 gen_context [type=GEN_CONTEXT]
    /usr/share/selinux/refpolicy/include/system/init.if: Syntax error on
    line 1416 ' [type=SQUOTE]
    /usr/share/selinux/refpolicy/include/system/init.if: Syntax error on
    line 1422 ' [type=SQUOTE]
