[PATCH] cfgfile: increase value length

[Vipin Varghese]

The default value for CFG_VALUE_LEN is set to 256 characters.
This limits the parsing for longer strings in configuration file.
Setting the default to 2048 characters increases the value array
size in `struct rte_cfgfile_entry`.

Files using cfgfile library are
1. drivers/net/mvpp2/
2. app/test-dma-perf/
3. app/test/
4. examples/qos_sched/

The structure `rte_cfgfile_entry` is not included in DPDK libraries.
Modifying from 256 to 2048 allows `app/test-dma-perf/main.c` helps to
parse longer string as shared in https://bugs.dpdk.org/show_bug.cgi?id=1333
