configure: Run SHFLAGS through ldflags_filter()

These flags are as linker-specific as other LDFLAGS and thus
need to be translated to the correct linker syntax.

The new name is more descriptive and will allow defining a separate
public prefix for externally visible library symbols.

lavfi: EBU R.128 irregular time

Correct the time interval between logged data rows to the expected
value of 100 milliseconds by naming a new loop counter variable
to be distinct from loop counters for inner loops that
inadvertently change the outer loop operation.

This suggested patch is 1 of 3 for Ticket #2144 "libavfilter ebur128
loudness inaccuracy, irregular time interval, LFE interference".
This suggested patch supersedes the contribution of January 15, 2013
in the thread “[PATCH] lavfi: EBU R.128 irreg time, ch weights, skip
LFE” which combined multiple fixes in one patch.
