sim: Fix sim m32 start up crash issue.

Browse source 
After compilation, when starting nsh, the following crash occurs.
==2500151==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
==2500151==ASan shadow was supposed to be located in the [0x1ffff000-0x3fffffff] range.
==2500151==Process memory map follows:
0x30000000-0x33dd4000 /nuttx/nuttx

To avoid overlaps, change the starting address of the text segment.

Using Ttext-segment=0x30000000 causes a crash when starting the 32-bit SIM.
Using -Ttext-segment=0x50000000 causes a crash when starting the 64-bit SIM.
Setting -Ttext-segment=0x40000000 resolves all issues perfectly.
