Indentation fixes, .SDSCTAG creates only sections

defines.h and wlalink/analyze.h contained some weird indentations. Made
.SDSCTAG to output just sections, so if one wants to change the place
where the data is put, just alter the addresses of the sections (e.g.
!__WLA_SDSCTAG_STRINGS and !__WLA_SDSCTAG_TIMEDATE) in WLALINK.
