Mathieu Duponchelle a7180e3995 libcaption: fix bit set on indent preambles
style preambles look like:

|P|0|0|1|C|0|ROW| |P|1|N|0|STYLE|U|

and column preambles look like:

|P|0|0|1|C|0|ROW| |P|1|N|1|CURSR|U|

Both preambles go through eia608_row_pramble(), the value they
pass as the x parameter is supposed to hold 4 bits, either
0|STYLE

or 1|CURSR

This value then gets bit-shifted by 1 and or'd in the second byte.

The value is also and' with 0x1E to ensure it can't leak into
the upper bits.

The previous code resulted in x being a 5-bit value, 0x10 (0b10000).
This resulted in outputting a style preamble, as 0x10 << 1 & 0x1E
is 0b00000. When the indent was 0 (the usual case), this went
undetected, but with any other value it resulted in no indent being
applied, but the text getting colored or italicized.

This patch fixes x to have the correct value of 0x8 | indent.
